Overview

The unique package provides facilities for canonicalizing (“interning”) comparable values.

​ unique 包提供了用于规范化（“驻留”）可比较值的功能。

类型

type Handle

type Handle[T comparable] struct {
	// contains filtered or unexported fields
}

Handle is a globally unique identity for some value of type T.

​ Handle 是某个类型为 T 的值的全局唯一标识。

Two handles compare equal exactly if the two values used to create the handles would have also compared equal. The comparison of two handles is trivial and typically much more efficient than comparing the values used to create them.

​ 当且仅当创建 Handle 的两个值相等时，两个 Handle 才相等。比较两个 Handle 的操作非常简单，通常比比较创建它们的值更加高效。

func Make

1

func Make[T comparable](value T) Handle[T]

Make returns a globally unique handle for a value of type T. Handles are equal if and only if the values used to produce them are equal.

​ Make 返回一个值类型为 T 的全局唯一 Handle。当且仅当用于生成 Handle 的值相等时，Handle 才相等。

(Handle[T]) Value

1

func (h Handle[T]) Value() T

Value returns a shallow copy of the T value that produced the Handle.

​ Value 返回生成 Handle 的 T 值的浅拷贝。
