# hashstructure [](https://godoc.org/github.com/mitchellh/hashstructure)
|
||||
|
||||
hashstructure is a Go library for creating a unique hash value
|
||||
for arbitrary values in Go.
|
||||
|
||||
This can be used to key values in a hash (for use in a map, set, etc.)
|
||||
that are complex. The most common use case is comparing two values without
|
||||
sending data across the network, caching values locally (de-dup), and so on.
|
||||
|
||||
## Features
|
||||
|
||||
* Hash any arbitrary Go value, including complex types.
|
||||
|
||||
* Tag a struct field to ignore it and not affect the hash value.
|
||||
|
||||
* Tag a slice type struct field to treat it as a set where ordering
|
||||
doesn't affect the hash code but the field itself is still taken into
|
||||
account to create the hash value.
|
||||
|
||||
* Optionally specify a custom hash function to optimize for speed, collision
|
||||
avoidance for your data set, etc.
|
||||
|
||||
* Optionally hash the output of `.String()` on structs that implement fmt.Stringer,
|
||||
allowing effective hashing of time.Time
|
||||
|
||||
## Installation
|
||||
|
||||
Standard `go get`:
|
||||
|
||||
```
|
||||
$ go get github.com/mitchellh/hashstructure
|
||||
```
|
||||
|
||||
## Usage & Example
|
||||
|
||||
For usage and examples see the [Godoc](http://godoc.org/github.com/mitchellh/hashstructure).
|
||||
|
||||
A quick code example is shown below:
|
||||
|
||||
```go
|
||||
type ComplexStruct struct {
|
||||
Name string
|
||||
Age uint
|
||||
Metadata map[string]interface{}
|
||||
}
|
||||
|
||||
v := ComplexStruct{
|
||||
Name: "mitchellh",
|
||||
Age: 64,
|
||||
Metadata: map[string]interface{}{
|
||||
"car": true,
|
||||
"location": "California",
|
||||
"siblings": []string{"Bob", "John"},
|
||||
},
|
||||
}
|
||||
|
||||
hash, err := hashstructure.Hash(v, nil)
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
|
||||
fmt.Printf("%d", hash)
|
||||
// Output:
|
||||
// 2307517237273902113
|

// Package mock provides a system by which it is possible to mock your objects
|
||||
// and verify calls are happening as expected.
|
||||
//
|
||||
// Example Usage
|
||||
//
|
||||
// The mock package provides an object, Mock, that tracks activity on another object. It is usually
|
||||
// embedded into a test object as shown below:
|
||||
//
|
||||
// type MyTestObject struct {
|
||||
// // add a Mock object instance
|
||||
// mock.Mock
|
||||
//
|
||||
// // other fields go here as normal
|
||||
// }
|
||||
//
|
||||
// When implementing the methods of an interface, you wire your functions up
|
||||
// to call the Mock.Called(args...) method, and return the appropriate values.
|
||||
//
|
||||
// For example, to mock a method that saves the name and age of a person and returns
|
||||
// the year of their birth or an error, you might write this:
|
||||
//
|
||||
// func (o *MyTestObject) SavePersonDetails(firstname, lastname string, age int) (int, error) {
|
||||
// args := o.Called(firstname, lastname, age)
|
||||
// return args.Int(0), args.Error(1)
|
||||
// }
|
||||
//
|
||||
// The Int, Error and Bool methods are examples of strongly typed getters that take the argument
|
||||
// index position. Given this argument list:
|
||||
//
|
||||
// (12, true, "Something")
|
||||
//
|
||||
// You could read them out strongly typed like this:
|
||||
//
|
||||
// args.Int(0)
|
||||
// args.Bool(1)
|
||||
// args.String(2)
|
||||
//
|
||||
// For objects of your own type, use the generic Arguments.Get(index) method and make a type assertion:
|
||||
//
|
||||
// return args.Get(0).(*MyObject), args.Get(1).(*AnotherObjectOfMine)
|
||||
//
|
||||
// This may cause a panic if the object you are getting is nil (the type assertion will fail), in those
|
||||
// cases you should check for nil first.
