Trait MapDerefExt

pub trait MapDerefExt: Deref + Sized {
    // Required method
    fn map_deref<F: Fn(&Self::Target) -> &T, T>(
        self,
        f: F,
    ) -> MapDeref<Self, T, F>;
}

A trait providing an easy way to instantiate MapDeref.

Required Methods

fn map_deref<F: Fn(&Self::Target) -> &T, T>(self, f: F) -> MapDeref<Self, T, F>

Maps this value from the current Deref::Target to T.

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.
