Trait Implementations

impl<T> Convert<T, T> for Identity

fn convert(a: T) -> T

Make conversion.

impl<T> ConvertBack<T, T> for Identity

fn convert_back(a: T) -> T

Make conversion back.

impl<T> MaybeConvert<T, T> for Identity

fn maybe_convert(a: T) -> Option<T>

Attempt to make conversion.

impl<T> MaybeConvertBack<T, T> for Identity

fn maybe_convert_back(a: T) -> Option<T>

Attempt to make conversion back.

impl<T: Clone> MaybeEquivalence<T, T> for Identity

fn convert(a: &T) -> Option<T>

Attempt to convert reference of A into value of B, returning None if not possible.

fn convert_back(a: &T) -> Option<T>

Attempt to convert reference of B into value of A, returning None if not possible.

impl<T> Morph<T> for Identity

A structure that performs identity conversion.

type Outcome = T

The type into which A is mutated.

fn morph(a: T) -> T

Make conversion.

impl<T> TryConvert<T, T> for Identity

fn try_convert(a: T) -> Result<T, T>

Attempt to make conversion. If returning Result::Err, the inner must always be a.

impl<T> TryConvertBack<T, T> for Identity

fn try_convert_back(a: T) -> Result<T, T>

Attempt to make conversion back. If returning Result::Err, the inner must always be b.

impl<T> TryMorph<T> for Identity

A structure that performs identity conversion.

type Outcome = T

The type into which A is mutated.

fn try_morph(a: T) -> Result<T, ()>

Make conversion.
