Struct ConditionHandler 

pub struct ConditionHandler { /* private fields */ }

A handler bound to a condition kind, prompt, and capture continuation.

Installed on a ConditionStack; when a matching Condition is signalled, its prompt and continuation drive the underlying control capture.

Implementations

impl ConditionHandler

pub fn new(kind: Symbol, prompt: Ref, continuation: Ref) -> Self

Builds a one-shot handler for kind bound to prompt and continuation.

pub fn multishot(self) -> Self

Returns a copy of this handler marked multishot (resumable more than once).

pub fn kind(&self) -> &Symbol

Returns the condition kind this handler matches.

pub fn prompt(&self) -> &Ref

Returns the prompt the handler captures against.

pub fn continuation(&self) -> &Ref

Returns the continuation resumed after the handler runs.

Trait Implementations

impl Clone for ConditionHandler

fn clone(&self) -> ConditionHandler

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConditionHandler

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

Formats the value using the given formatter.

impl Eq for ConditionHandler

impl PartialEq for ConditionHandler

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