Trait sp_runtime::traits::TryMorph

pub trait TryMorph<A> {
    type Outcome;

    // Required method
    fn try_morph(a: A) -> Result<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 try_morph(a: A) -> Result<Self::Outcome, ()>

Make conversion.

Object Safety

This trait is not object safe.

Implementors

impl<L: TypedGet, M> TryMorph<<L as TypedGet>::Type> for MorphWithUpperLimit<L, M>where L::Type: Ord, M: TryMorph<L::Type, Outcome = L::Type>,

type Outcome = <L as TypedGet>::Type

impl<N: TypedGet> TryMorph<<N as TypedGet>::Type> for CheckedReduceBy<N>where N::Type: CheckedSub,

type Outcome = <N as TypedGet>::Type

impl<N: TypedGet> TryMorph<<N as TypedGet>::Type> for ReduceBy<N>where N::Type: CheckedSub + Zero,

type Outcome = <N as TypedGet>::Type

impl<T> TryMorph<T> for Identity

A structure that performs identity conversion.

type Outcome = T

impl<T, A: TryInto<T>> TryMorph<A> for TryMorphInto<T>

type Outcome = T

impl<V: TypedGet, X> TryMorph<X> for Replace<V>

type Outcome = <V as TypedGet>::Type
