Trait polkadot_sdk_frame::traits::IsType

pub trait IsType<T>: Into<T> + From<T> {
    // Required methods
    fn from_ref(t: &T) -> &Self;
    fn into_ref(&self) -> &T;
    fn from_mut(t: &mut T) -> &mut Self;
    fn into_mut(&mut self) -> &mut T;
}

Trait to be used when types are exactly same.

This allow to convert back and forth from type, a reference and a mutable reference.

fn from_ref(t: &T) -> &Self

Cast reference.

fn into_ref(&self) -> &T

Cast reference.

fn from_mut(t: &mut T) -> &mut Self

Cast mutable reference.

fn into_mut(&mut self) -> &mut T

Cast mutable reference.
