Trait Implementations

impl<E: Debug, R: Debug> Debug for Execution<E, R>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<E, R> Default for Execution<E, R>

fn default() -> Execution<E, R>

Returns the “default value” for a type.

impl<E, R> From<E> for Execution<E, R>

fn from(original: E) -> Execution<E, R>

Converts to this type from the input type.

impl<E, R> FromResidual<Option<Infallible>> for Execution<E, R>

fn from_residual(residual: Option<Infallible>) -> Self

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

Constructs the type from a compatible Residual type.

impl<E1: Into<E2>, E2, R> FromResidual<Result<Infallible, E1>> for Execution<E2, R>

fn from_residual(residual: Result<Infallible, E1>) -> Self

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

Constructs the type from a compatible Residual type.

impl<E, R> FromResidual for Execution<E, R>

fn from_residual(residual: <Self as Try>::Residual) -> Self

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

Constructs the type from a compatible Residual type.

impl<E, R> Try for Execution<E, R>

type Output = R

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

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

type Residual = Skip<E>

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

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

fn from_output(output: Self::Output) -> Self

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

Constructs the type from its Output type.

fn branch(self) -> ControlFlow<Self::Residual, Self::Output>

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

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).
