Equal returns true iff protocol buffers a and b are equal.
The arguments must both be pointers to protocol buffer structs.
Equality is defined in this way:
- Two messages are equal iff they are the same type,
corresponding fields are equal, unknown field sets
are equal, and extensions sets are equal.
- Two set scalar fields are equal iff their values are equal.
If the fields are of a floating-point type, remember that
NaN != x for all x, including NaN. If the message is defined
in a proto3 .proto file, fields are not "set"; specifically,
zero length proto3 "bytes" fields are equal (nil == {}).
- Two repeated fields are equal iff their lengths are the same,
and their corresponding elements are equal. Note a "bytes" field,
although represented by []byte, is not a repeated field and the
rule for the scalar fields described above applies.
- Two unset fields are equal.
- Two unknown field sets are equal if their current
encoded state is equal.
- Two extension sets are equal iff they have corresponding
elements that are pairwise equal.
- Two map fields are equal iff their lengths are the same,
and they contain the same set of elements. Zero-length map
fields are equal.
- Every other combination of things are not equal.
The return value is undefined if a and b are not protocol buffers.

/*
Package proto converts data structures to and from the wire format of
protocol buffers. It works in concert with the Go source code generated
for .proto files by the protocol compiler.
A summary of the properties of the protocol buffer interface
for a protocol buffer variable v:
- Names are turned from camel_case to CamelCase for export.
- There are no methods on v to set fields; just treat
them as structure fields.
- There are getters that return a field's value if set,
and return the field's default value if unset.
The getters work even if the receiver is a nil message.
- The zero value for a struct is its correct initialization state.
All desired fields must be set before marshaling.
- A Reset() method will restore a protobuf struct to its zero state.
- Non-repeated fields are pointers to the values; nil means unset.
That is, optional or required field int32 f becomes F *int32.
- Repeated fields are slices.
- Helper functions are available to aid the setting of fields.
msg.Foo = proto.String("hello") // set field
- Constants are defined to hold the default values of all fields that
have them. They have the form Default_StructName_FieldName.
Because the getter methods handle defaulted values,
direct use of these constants should be rare.
- Enums are given type names and maps from names to values.
Enum values are prefixed by the enclosing message's name, or by the
enum's type name if it is a top-level enum. Enum types have a String
method, and a Enum method to assist in message construction.
- Nested messages, groups and enums have type names prefixed with the name of
the surrounding message type.
- Extensions are given descriptor names that start with E_,
followed by an underscore-delimited list of the nested messages
that contain it (if any) followed by the CamelCased name of the
extension field itself. HasExtension, ClearExtension, GetExtension
and SetExtension are functions for manipulating extensions.
- Oneof field sets are given a single field in their message,
with distinguished wrapper types for each possible field value.
- Marshal and Unmarshal are functions to encode and decode the wire format.
When the .proto file specifies `syntax="proto3"`, there are some differences:
- Non-repeated fields of non-message type are values instead of pointers.
- Enum types do not get an Enum method.
The simplest way to describe this is to see an example.
Given file test.proto, containing
package example;
enum FOO { X = 17; }
message Test {
required string label = 1;
optional int32 type = 2 [default=77];
repeated int64 reps = 3;
optional group OptionalGroup = 4 {
required string RequiredField = 5;
}
oneof union {
int32 number = 6;
string name = 7;

glog
====
Leveled execution logs for Go.
This is an efficient pure Go implementation of leveled logs in the
manner of the open source C++ package
https://github.com/google/glog
By binding methods to booleans it is possible to use the log package
without paying the expense of evaluating the arguments to the log.
Through the -vmodule flag, the package also provides fine-grained
control over logging at the file level.
The comment from glog.go introduces the ideas:
Package glog implements logging analogous to the Google-internal
C++ INFO/ERROR/V setup. It provides functions Info, Warning,
Error, Fatal, plus formatting variants such as Infof. It
also provides V-style logging controlled by the -v and
-vmodule=file=2 flags.
Basic examples:
glog.Info("Prepare to repel boarders")
glog.Fatalf("Initialization failed: %s", err)
See the documentation for the V function for an explanation
of these examples:
if glog.V(2) {
glog.Info("Starting transaction...")
}
glog.V(2).Infoln("Processed", nItems, "elements")
The repository contains an open source version of the log package
used inside Google. The master copy of the source lives inside
Google, not here. The code in this repo is for export only and is not itself
under development. Feature requests will be ignored.

# How to contribute #
We'd love to accept your patches and contributions to this project. There are
a just a few small guidelines you need to follow.
## Contributor License Agreement ##
Contributions to any Google project must be accompanied by a Contributor
License Agreement. This is not a copyright **assignment**, it simply gives
Google permission to use and redistribute your contributions as part of the
project.
* If you are an individual writing original source code and you're sure you
own the intellectual property, then you'll need to sign an [individual
CLA][].
* If you work for a company that wants to allow you to contribute your work,
then you'll need to sign a [corporate CLA][].
You generally only need to submit a CLA once, so if you've already submitted
one (even if it was for a different project), you probably don't need to do it
again.
[individual CLA]: https://developers.google.com/open-source/cla/individual
[corporate CLA]: https://developers.google.com/open-source/cla/corporate
## Submitting a patch ##
1. It's generally best to start by opening a new issue describing the bug or
feature you're intending to fix. Even if you think it's relatively minor,
it's helpful to know what people are working on. Mention in the initial
issue that you are planning to work on that bug or feature so that it can
be assigned to you.
1. Follow the normal process of [forking][] the project, and setup a new
branch to work in. It's important that each group of changes be done in
separate branches in order to ensure that a pull request only includes the
commits related to that bug or feature.
1. Go makes it very simple to ensure properly formatted code, so always run
`go fmt` on your code before committing it. You should also run
[golint][] over your code. As noted in the [golint readme][], it's not
strictly necessary that your code be completely "lint-free", but this will
help you find common style issues.
1. Any significant changes should almost always be accompanied by tests. The
project already has good test coverage, so look at some of the existing
tests if you're unsure how to go about it. [gocov][] and [gocov-html][]
are invaluable tools for seeing which parts of your code aren't being
exercised by your tests.
1. Do your best to have [well-formed commit messages][] for each change.
This provides consistency throughout the project, and ensures that commit
messages are able to be formatted properly by various git tools.
1. Finally, push the commits to your fork and submit a [pull request][].

gofuzz
======
gofuzz is a library for populating go objects with random values.
[![GoDoc](https://godoc.org/github.com/google/gofuzz?status.png)](https://godoc.org/github.com/google/gofuzz)
[![Travis](https://travis-ci.org/google/gofuzz.svg?branch=master)](https://travis-ci.org/google/gofuzz)
This is useful for testing:
* Do your project's objects really serialize/unserialize correctly in all cases?
* Is there an incorrectly formatted object that will cause your project to panic?
Import with ```import "github.com/google/gofuzz"```
You can use it on single variables:
```go
f := fuzz.New()
var myInt int
f.Fuzz(&myInt) // myInt gets a random value.
```
You can use it on maps:
```go
f := fuzz.New().NilChance(0).NumElements(1, 1)
var myMap map[ComplexKeyType]string
f.Fuzz(&myMap) // myMap will have exactly one element.
```
Customize the chance of getting a nil pointer:
```go
f := fuzz.New().NilChance(.5)
var fancyStruct struct {
A, B, C, D *string
}
f.Fuzz(&fancyStruct) // About half the pointers should be set.
```
You can even customize the randomization completely if needed:
```go
type MyEnum string
const (
A MyEnum = "A"
B MyEnum = "B"
)
type MyInfo struct {
Type MyEnum
AInfo *string
BInfo *string
}
f := fuzz.New().NilChance(0).Funcs(
func(e *MyInfo, c fuzz.Continue) {
switch c.Intn(2) {
case 0:
e.Type = A
c.Fuzz(&e.AInfo)
case 1:
e.Type = B
c.Fuzz(&e.BInfo)
}
},
)
var myObject MyInfo
f.Fuzz(&myObject) // Type will correspond to whether A or B info is set.
```
See more examples in ```example_test.go```.
Happy testing!

A high-performance 100% compatible drop-in replacement of "encoding/json"
You can also use thrift like JSON using [thrift-iterator](https://github.com/thrift-iterator/go)
# Benchmark
![benchmark](http://jsoniter.com/benchmarks/go-benchmark.png)
Source code: https://github.com/json-iterator/go-benchmark/blob/master/src/github.com/json-iterator/go-benchmark/benchmark_medium_payload_test.go
Raw Result (easyjson requires static code generation)
| | ns/op | allocation bytes | allocation times |
| --- | --- | --- | --- |
| std decode | 35510 ns/op | 1960 B/op | 99 allocs/op |
| easyjson decode | 8499 ns/op | 160 B/op | 4 allocs/op |
| jsoniter decode | 5623 ns/op | 160 B/op | 3 allocs/op |
| std encode | 2213 ns/op | 712 B/op | 5 allocs/op |
| easyjson encode | 883 ns/op | 576 B/op | 3 allocs/op |
| jsoniter encode | 837 ns/op | 384 B/op | 4 allocs/op |
Always benchmark with your own workload.
The result depends heavily on the data input.
# Usage
100% compatibility with standard lib
Replace
```go
import "encoding/json"
json.Marshal(&data)
```
with
```go
import "github.com/json-iterator/go"
var json = jsoniter.ConfigCompatibleWithStandardLibrary
json.Marshal(&data)
```
Replace
```go
import "encoding/json"
json.Unmarshal(input, &data)
```
with
```go
import "github.com/json-iterator/go"
var json = jsoniter.ConfigCompatibleWithStandardLibrary
json.Unmarshal(input, &data)
```
