@corpsmoderne You can't. It borrows from a value created inside the function. You can only return temporary references to values that existed before the function has been called.

@corpsmoderne You could try to return a `Span<'static>` like https://play.rust-lang.org/?version=stable&mode=debug&edition=2024. Maybe the last line in https://docs.rs/ratatui/latest/ratatui/text/struct.Span.html#method.styled works?

@kornel ha, sorry that was the "I'm tired" part of the post. I didn't realize it borrowed from bat_s. So this should work:
fn display_battery_level<'a>(bat: f32, bat_s: &'a str) -> Span<'a> {
match bat {
_ if bat > 50.0 => bat_s.green(),
_ if bat > 25.0 => bat_s.yellow(),
_ => bat_s.red(),
}
}
