Macro esp_idf_svc::hal::sys::const_format::str_repeat

macro_rules! str_repeat {
    ($string:expr, $times:expr  $(,)*) => { ... };
}

Creates a &'static str by repeating a &'static str constant times times

This is evaluated at compile-time.

Example

use const_format::str_repeat;

{
    const OUT: &str = str_repeat!("hi ", 4);
    assert_eq!(OUT, "hi hi hi hi ")
}
{
    const IN: &str = "bye ";
    const REPEAT: usize = 5;
    const OUT: &str = str_repeat!(IN, REPEAT);
    assert_eq!(OUT, "bye bye bye bye bye ")
}

Failing

If this macro would produce too large a string, it causes a compile-time error.

const_format::str_repeat!("hello", usize::MAX / 4);
