use core::fmt;

/// Format a string lazily.

/// This is cheap, like [`format_args`], but doesn't cause temporary lifetime issues, allowing
/// it to be easily used in let bindings.
/// See <https://github.com/rust-lang/rust/issues/92698> for more information about this.
///
/// This works by storing a callback that will be invoked when [`Display::fmt`](fmt::Display::fmt)
/// is called. As such, format arguments may be evaluated multiple times.
