Struct core::ops::try_trait::NeverShortCircuit

#[repr(transparent)]
pub(crate) struct NeverShortCircuit<T>(pub T);

An adapter for implementing non-try methods via the Try implementation.

Conceptually the same as Result<T, !>, but requiring less work in trait solving and inhabited-ness checking and such, by being an obvious newtype and not having From bounds lying around.

Not currently planned to be exposed publicly, so just pub(crate).

Implementations

impl<T> NeverShortCircuit<T>

pub const fn wrap_mut_2_imp<A, B, F: FnMut(A, B) -> T>(
    f: &mut F,
    (a, b): (A, B)
) -> NeverShortCircuit<T>

Implementation for building ConstFnMutClosure for wrapping the output of a ~const FnMut in a NeverShortCircuit.

Trait Implementations

impl<T> FromResidual<<NeverShortCircuit<T> as Try>::Residual> for NeverShortCircuit<T>

const fn from_residual(never: NeverShortCircuitResidual) -> Self

🔬This is a nightly-only experimental API. (try_trait_v2 #84277)

Constructs the type from a compatible Residual type.

impl<T> Try for NeverShortCircuit<T>

type Output = T

🔬This is a nightly-only experimental API. (try_trait_v2 #84277)

The type of the value produced by ? when not short-circuiting.

type Residual = NeverShortCircuitResidual

🔬This is a nightly-only experimental API. (try_trait_v2 #84277)

The type of the value passed to FromResidual::from_residual as part of ? when short-circuiting.

const fn branch(self) -> ControlFlow<NeverShortCircuitResidual, T>

🔬This is a nightly-only experimental API. (try_trait_v2 #84277)

Used in ? to decide whether the operator should produce a value (because this returned ControlFlow::Continue) or propagate a value back to the caller (because this returned ControlFlow::Break).

const fn from_output(x: T) -> Self

🔬This is a nightly-only experimental API. (try_trait_v2 #84277)

Constructs the type from its Output type.
