Struct ControlAbort 

pub struct ControlAbort {
    pub prompt: Ref,
    pub value: Ref,
    pub result_shape: Ref,
}

Record describing an abort that unwinds to a prompt with a value.

Fields

prompt: Ref

Reference identifying the prompt boundary to unwind to.

value: Ref

Value delivered as the prompt result.

result_shape: Ref

Shape the prompt result must satisfy.

Implementations

impl ControlAbort

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

Build an abort record from its prompt, value, and result shape.

Trait Implementations

impl Clone for ControlAbort

fn clone(&self) -> ControlAbort

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ControlAbort

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

Formats the value using the given formatter.

impl Eq for ControlAbort

impl PartialEq for ControlAbort

fn eq(&self, other: &ControlAbort) -> 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.
