Macro to_str

macro_rules! to_str {
    ($x: expr) => { ... };
}

Converts a value to a string slice.

The input type must be one of

• &str
• char
• bool
• u8, u16, u32, u64, u128, usize
• i8, i16, i32, i64, i128, isize

This macro is const-context only.

Examples

const A: &str = const_str::to_str!("A");
assert_eq!(A, "A");

const B: &str = const_str::to_str!('我');
assert_eq!(B, "我");

const C: &str = const_str::to_str!(true);
assert_eq!(C, "true");

const D: &str = const_str::to_str!(1_u8 + 1);
assert_eq!(D, "2");

const E: &str = const_str::to_str!(-21_i32 * 2);
assert_eq!(E, "-42")
