指向地图的指针 [英] Pointer to a map

问题描述

将一些贴图定义为：

  var valueToSomeType = map [uint8] someType {...} 
 var nameToSomeType = map [string] someType {...} 
  

我想要一个变量指向地图的地址（不要复制所有变量）。我试过它：

  valueTo：=& valueToSomeType 
 nameTo：=& nameToSomeType 
  

但使用 valueTo [number] 时，它显示

内部编译器错误：var without type，init：new

如何获取它？

编辑

错误是由另一个问题所显示的。 h2_lin>解决方案

地图是引用类型，因此它们都是通过引用传递的。你不需要指针。

Having some maps defined as:

var valueToSomeType = map[uint8]someType{...}
var nameToSomeType = map[string]someType{...}

I would want a variable that points to the address of the maps (to don't copy all variable). I tried it using:

valueTo := &valueToSomeType
nameTo := &nameToSomeType

but at using valueTo[number], it shows
internal compiler error: var without type, init: new

How to get it?

Edit

The error was showed by another problem.

解决方案

Maps are reference types, so they are allways passed by reference. You don't need a pointer.
