Enum std::ops::ControlFlow

pub enum ControlFlow<C, B> {
    Continue(C),
    Break(B),
}

🔬 This is a nightly-only experimental API. (control_flow_enum #75744)

new API

Used to make try_fold closures more like normal loops

Variants

Continue(C)

🔬 This is a nightly-only experimental API. (control_flow_enum #75744)

new API

Continue in the loop, using the given value for the next iteration

Break(B)

🔬 This is a nightly-only experimental API. (control_flow_enum #75744)

new API

Exit the loop, yielding the given value

Implementations

impl<C, B> ControlFlow<C, B>

pub fn break_value(self) -> Option<B>

🔬 This is a nightly-only experimental API. (control_flow_enum #75744)

new API

Converts the ControlFlow into an Option which is Some if the ControlFlow was Break and None otherwise.

impl<R> ControlFlow<<R as Try>::Ok, R> where
    R: Try, 

pub fn from_try(r: R) -> ControlFlow<<R as Try>::Ok, R>

🔬 This is a nightly-only experimental API. (control_flow_enum #75744)

new API

Create a ControlFlow from any type implementing Try.

pub fn into_try(self) -> R

🔬 This is a nightly-only experimental API. (control_flow_enum #75744)

new API

Convert a ControlFlow into any type implementing Try;
