Trait Implementations

impl<T> Debug for Ready<T>

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

使用给定的格式化程序格式化该值。

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

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

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

从兼容的 Residual 类型构造类型。

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

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

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

从兼容的 Residual 类型构造类型。

impl<T> Try for Ready<T>

type Output = T

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

当不短路时，? 产生的值的类型。

type Residual = Ready<Infallible>

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

短路时作为 ? 的一部分传递给 FromResidual::from_residual 的值的类型。

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

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

从它的 Output 类型构造类型。

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

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

在 ? 来决定操作符是应该生成一个值 (因为它返回了 ControlFlow::Continue)，还是将一个值传播回调用者 (因为它返回了 ControlFlow::Break)。
