Struct lightproc::proc_handle::ProcHandle

pub struct ProcHandle<R> { /* fields omitted */ }

A handle that awaits the result of a proc.

This type is a future that resolves to an Option<R> where:

• None indicates the proc has panicked or was cancelled
• Some(res) indicates the proc has completed with res

Methods

impl<R> ProcHandle<R>

pub fn cancel(&self)

Cancels the proc.

If the proc has already completed, calling this method will have no effect.

When a proc is cancelled, its future cannot be polled again and will be dropped instead.

pub fn stack(&self) -> &ProcStack

Returns a reference to the stack stored inside the proc.
