Struct ControlCapture 

pub struct ControlCapture {
    pub prompt: Ref,
    pub continuation: Ref,
    pub value: Ref,
    pub result_shape: Ref,
    pub multishot: bool,
}

Record describing a capture of the continuation up to a prompt.

Fields

prompt: Ref

Reference identifying the prompt boundary captured up to.

continuation: Ref

Reference to the captured continuation.

value: Ref

Value delivered to the captured continuation.

result_shape: Ref

Shape the resumed result must satisfy.

multishot: bool

Whether the continuation may be resumed more than once.

Implementations

impl ControlCapture

pub fn new( prompt: Ref, continuation: Ref, value: Ref, result_shape: Ref, ) -> Self

Build a single-shot capture record.

pub fn multishot(self) -> Self

Mark the capture as resumable more than once.

Trait Implementations

impl Clone for ControlCapture

fn clone(&self) -> ControlCapture

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ControlCapture

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

Formats the value using the given formatter.

impl Eq for ControlCapture

impl PartialEq for ControlCapture

fn eq(&self, other: &ControlCapture) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
