Struct InterruptHandle 

pub struct InterruptHandle { /* private fields */ }

Cooperative interrupt signal shared between the SLYNK reader task (which interrupt()s on (:emacs-interrupt)) and the eval task. Backed by a monotonic generation counter rather than a boolean latch: an interrupt increments the count, and a request asks “did the count move since I started?” via InterruptHandle::generation + [InterruptHandle::is_interrupted_since].

The generation design is deliberate (a prior boolean latch was racy): there is no shared flag to leave set, so an interrupt can never “stick” and poison an unrelated later request. Each top-level operation snapshots the generation at entry and compares against it; the next operation re-snapshots, automatically discarding any interrupt that targeted the finished one — no per-exit cleanup needed, on any terminal path.

Implementations

impl InterruptHandle

pub fn interrupt(&self)

Signals an interrupt by advancing the generation. Idempotent in effect: any request whose baseline predates this call observes the interrupt.

Trait Implementations

impl Clone for InterruptHandle

fn clone(&self) -> InterruptHandle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InterruptHandle

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

Formats the value using the given formatter.

impl Default for InterruptHandle

fn default() -> InterruptHandle

Returns the “default value” for a type.
