Macro arcstr::format

macro_rules! format {
    ($text : expr $(,) ?) => { ... };
    ($text : expr, $($toks : tt) +) => { ... };
}

Conceptually equivalent to ArcStr::from(format!("...", args...)).

Currently, the only difference here is that when used with no formatting args, this behaves equivalently to arcstr::literal!.

In the future, this will be implemented in such a way to avoid an additional string copy which is required by the from operation.

Example

let arcstr = arcstr::format!("testing {}", 123);
assert_eq!(arcstr, "testing 123");
