Crate wchar

A procedural macro for compile time UTF-16 wide strings.

This crate introduces two macros wch! and wch_c! to create UTF-16 wide strings at compiler time, like the L literal in C.

In order to use the macro the proc_macro and proc_macro_non_items features must be enabled.

Examples

use wchar::{wch, wch_c};

// Equivalent to `#define RUST L"Rust"` in C.
const RUST: &[u16] = wch!("Rust\0"); // C strings are null-terminated.
assert_eq!(RUST, &[0x0052, 0x0075, 0x0073, 0x0074, 0x0000]);

// Equivalent to `#define ALSO_RUST L"Rust"` in C.
const ALSO_RUST: &[u16] = wch_c!("Rust");
assert_eq!(ALSO_RUST, &[0x0052, 0x0075, 0x0073, 0x0074, 0x0000]);

Macros

wch	Generate a UTF-16 wide string from the given string literal.
wch_c	Generate a C-style nul-terminated UTF-16 wide string from the given string literal.
