如何在Rust中创建字符串的全局静态数组?

How do you create a global static array of strings in Rust?

对于整数，它将编译:

static ONE:u8 = 1;
static TWO:u8 = 2;
static ONETWO:[&'static u8, ..2] = [&ONE, &TWO];

但是我无法得到类似的字符串来编译:

But I can't get something similar for strings to compile:

static STRHELLO:&'static str = "Hello";
static STRWORLD:&'static str = "World";
static ARR:[&'static str, ..2] = [STRHELLO,STRWORLD]; // Error: Cannot refer to the interior of another static

推荐答案

这是Rust 1.0及其后续版本的稳定替代方案:

This is a stable alternative for Rust 1.0 and every subsequent version:

const BROWSERS: &'static [&'static str] = &["firefox", "chrome"];
