Struct std::task::Ready

pub struct Ready<T>(_);

🔬This is a nightly-only experimental API. (poll_ready #89780)

Extracts the successful type of a Poll<T>.

See Poll::ready for details.

Trait Implementations

impl<T> Debug for Ready<T>

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

Formats the value using the given formatter.

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

fn from_residual(residual: Ready<Infallible>) -> Ready<T>

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

Constructs the type from a compatible Residual type.

impl<T> FromResidual<Ready<Infallible>> for Poll<T>

fn from_residual(residual: Ready<Infallible>) -> Poll<T>

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

Constructs the type from a compatible Residual type.

impl<T> Try for Ready<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 = Ready<Infallible>

🔬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.

fn from_output(output: <Ready<T> as Try>::Output) -> Ready<T>

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

Constructs the type from its Output type.

fn branch(
    self
) -> ControlFlow<<Ready<T> as Try>::Residual, <Ready<T> as Try>::Output>

🔬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).
