Trait IsWrappedBy

pub trait IsWrappedBy<Outer>: From<Outer> + Into<Outer> {
    // Required methods
    fn from_ref(outer: &Outer) -> &Self;
    fn from_mut(outer: &mut Outer) -> &mut Self;
}

One type is wrapped by another.

Required Methods

fn from_ref(outer: &Outer) -> &Self

Get a reference to the inner from the outer.

fn from_mut(outer: &mut Outer) -> &mut Self

Get a mutable reference to the inner from the outer.

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.
