Enum tear::twist_impl::Looping

pub enum Looping<T, B> {
    Resume(T),
    Break {
        label: Option<usize>,
    },
    BreakVal {
        label: Option<usize>,
        value: B,
    },
    Continue {

Different loop control signals that twist! understands

We map break, break $value and continue to types.

Variants

Resume(T)

Resume loop execution with value of type T

Break

Break a loop selected by label

Fields of Break

label: Option<usize>

The index of the label of the loop to break from. None means innermost loop

BreakVal

Break a loop selected by label with a value of value

Fields of BreakVal

label: Option<usize>

The index of the label of the loop to break from. None means innermost loop

value: B

The value to break with

Continue

Skip to the next iteration of the loop selected by label

Fields of Continue

label: Option<usize>

The index of the label of the loop to continue from. None means innermost loop

Trait Implementations

impl<T: Clone, B: Clone> Clone for Looping<T, B>
