Trait ActingClosures

pub trait ActingClosures<T, U> {
    // Required methods
    fn apply<F>(self, closure: F) -> U
       where F: Fn(T) -> U;
    fn also<F>(self, closure: F) -> T
       where F: Fn(&T);
}

Trait for closures acting on a generic type

Required Methods

fn apply<F>(self, closure: F) -> U

where F: Fn(T) -> U,

returns a new value returned by the closure

fn also<F>(self, closure: F) -> T

where F: Fn(&T),

returns the value on which the closure is applied

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
