Trait regex::Replacer

pub trait Replacer {
    fn reg_replace<'a>(&'a mut self, caps: &Captures) -> Cow<'a, str>;
}

Replacer describes types that can be used to replace matches in a string.

Required Methods

fn reg_replace<'a>(&'a mut self, caps: &Captures) -> Cow<'a, str>

Returns a possibly owned string that is used to replace the match corresponding to the caps capture group.

The 'a lifetime refers to the lifetime of a borrowed string when a new owned string isn't needed (e.g., for NoExpand).

Implementors

• impl<'t> Replacer for NoExpand<'t>
• impl<'t> Replacer for &'t str
• impl<F> Replacer for F where F: FnMut(&Captures) -> String
