utf16_lit

提供将utf8重新编码为utf16的macro_rules。

lib.rs:

提供创建utf-16字面量的macro_rules。

输出是正确大小的数组。在宏前加上&来创建切片。

use utf16_lit::{utf16, utf16_null};

const EXAMPLE: &[u16] = &utf16!("example");

const EXAMPLE_NULL: &[u16] = &utf16_null!("example");

fn main() {
  let v: Vec<u16> = "example".encode_utf16().collect();
  assert_eq!(v, EXAMPLE);

  let v: Vec<u16> = "example".encode_utf16().chain(Some(0)).collect();
  assert_eq!(v, EXAMPLE_NULL);
  let v: Vec<u16> = "example\0".encode_utf16().collect();
  assert_eq!(v, EXAMPLE_NULL);

  // You don't even need to assign the output to a const.
  assert_eq!(utf16!("This works")[0], 'T' as u8 as u16);
}
