Macro append 

macro_rules! append {
    ($dst:expr, $($arg:tt)*) => { ... };
}

Push formatted content to a string using write!.

Works on both std::string::String and CompactString (anything implementing std::fmt::Write).

Examples

use vize_l0::append;

let mut s = String::new();
let name = "world";
append!(s, "Hello, {name}!");
assert_eq!(s, "Hello, world!");
