Trait polkadot_sdk_frame::traits::Morph

pub trait Morph<A> {
    type Outcome;

    // Required method
    fn morph(a: A) -> Self::Outcome;
}

Extensible conversion trait. Generic over only source type, with destination type being associated.

Required Associated Types

type Outcome

The type into which A is mutated.

Required Methods

fn morph(a: A) -> Self::Outcome

Make conversion.

Object Safety

This trait is not object safe.
