Trait Replace 

pub trait Replace<'a> {
    // Required methods
    fn replace_cow<P: Pattern>(self, from: P, to: &str) -> Cow<'a, str>;
    fn replacen_cow<P: Pattern>(
        self,
        from: P,
        to: &str,
        count: usize,
    ) -> Cow<'a, str>;
}

Available on crate feature alloc only.

To extend str and Cow<str> to have replace_cow and replacen_cow methods.

Required Methods

fn replace_cow<P: Pattern>(self, from: P, to: &str) -> Cow<'a, str>

Replaces all matches of a pattern with another string, returning a Cow<str> to avoid allocation when possible.

fn replacen_cow<P: Pattern>( self, from: P, to: &str, count: usize, ) -> Cow<'a, str>

Replaces at most count matches of a pattern with another string, returning a Cow<str> to avoid allocation when possible.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
