Macro flexstr::flex_ufmt

macro_rules! flex_ufmt {
    ($($arg:tt)*) => { ... };
}

Equivalent to flex_fmt except that it uses ufmt which is much faster, but has limitations. See ufmt docs for more details

use flexstr::{flex_str, flex_ufmt};

let a = flex_ufmt!("Is {}{}", flex_str!("inlined"), "!");
assert!(a.is_inlined());
assert_eq!(a, "Is inlined!");
