[−][src]Enum nom::lib::std::ops::ControlFlow
🔬 This is a nightly-only experimental API. (control_flow_enum)
new API
Used to make try_fold closures more like normal loops
Variants
🔬 This is a nightly-only experimental API. (control_flow_enum)
new API
Continue in the loop, using the given value for the next iteration
🔬 This is a nightly-only experimental API. (control_flow_enum)
new API
Exit the loop, yielding the given value
Implementations
impl<B, C> ControlFlow<B, C>[src]
pub fn is_break(&self) -> bool[src]
🔬 This is a nightly-only experimental API. (control_flow_enum)
new API
Returns true if this is a Break variant.
pub fn is_continue(&self) -> bool[src]
🔬 This is a nightly-only experimental API. (control_flow_enum)
new API
Returns true if this is a Continue variant.
pub fn break_value(self) -> Option<B>[src]
🔬 This is a nightly-only experimental API. (control_flow_enum)
new API
Converts the ControlFlow into an Option which is Some if the
ControlFlow was Break and None otherwise.
impl<R> ControlFlow<R, <R as Try>::Ok> where
R: Try, [src]
R: Try,
pub fn from_try(r: R) -> ControlFlow<R, <R as Try>::Ok>[src]
🔬 This is a nightly-only experimental API. (control_flow_enum)
new API
Create a ControlFlow from any type implementing Try.
pub fn into_try(self) -> R[src]
🔬 This is a nightly-only experimental API. (control_flow_enum)
new API
Convert a ControlFlow into any type implementing Try;
impl<B> ControlFlow<B, ()>[src]
pub const CONTINUE: ControlFlow<B, ()>[src]
🔬 This is a nightly-only experimental API. (control_flow_enum)
new API
It's frequently the case that there's no value needed with Continue,
so this provides a way to avoid typing (()), if you prefer it.
Examples
#![feature(control_flow_enum)] use std::ops::ControlFlow; let mut partial_sum = 0; let last_used = (1..10).chain(20..25).try_for_each(|x| { partial_sum += x; if partial_sum > 100 { ControlFlow::Break(x) } else { ControlFlow::CONTINUE } }); assert_eq!(last_used.break_value(), Some(22));
impl<C> ControlFlow<(), C>[src]
pub const BREAK: ControlFlow<(), C>[src]
🔬 This is a nightly-only experimental API. (control_flow_enum)
new API
APIs like try_for_each don't need values with Break,
so this provides a way to avoid typing (()), if you prefer it.
Examples
#![feature(control_flow_enum)] use std::ops::ControlFlow; let mut partial_sum = 0; (1..10).chain(20..25).try_for_each(|x| { if partial_sum > 100 { ControlFlow::BREAK } else { partial_sum += x; ControlFlow::CONTINUE } }); assert_eq!(partial_sum, 108);
