Macro flexstr::a_flex_ufmt

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

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

use flexstr::{a_flex_str, a_flex_ufmt};

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