Trait ApplyMut 

pub trait ApplyMut<T> {
    type Cont<_T>;

    // Required method
    fn apply_mut<F>(&mut self, rhs: F) -> &mut Self::Cont<T>
       where F: FnMut(&mut T);
}

The ApplyMut trait allows for in-place mapping of a mutable reference to a type T

Required Associated Types

type Cont<_T>

Required Methods

fn apply_mut<F>(&mut self, rhs: F) -> &mut Self::Cont<T>

where F: FnMut(&mut T),

Dyn Compatibility

This trait is not dyn compatible.

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