Trait Implementations§

impl<A: Clone + TryInto<B>, B> MaybeConvert<A, B> for TryConvertInto

fn maybe_convert(a: A) -> Option<B>

Attempt to make conversion.

impl<A: Clone + TryInto<B>, B: Clone + TryInto<A>> MaybeConvertBack<A, B> for TryConvertInto

fn maybe_convert_back(b: B) -> Option<A>

Attempt to make conversion back.

impl<A: Clone + TryInto<B>, B: Clone + TryInto<A>> MaybeEquivalence<A, B> for TryConvertInto

fn convert(a: &A) -> Option<B>

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

fn convert_back(b: &B) -> Option<A>

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

impl<A: Clone + TryInto<B>, B> TryConvert<A, B> for TryConvertInto

fn try_convert(a: A) -> Result<B, A>

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

impl<A: Clone + TryInto<B>, B: Clone + TryInto<A>> TryConvertBack<A, B> for TryConvertInto

fn try_convert_back(b: B) -> Result<A, B>

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