Trait revent::Suspend

pub trait Suspend {
    fn suspend<F: FnOnce() -> R, R>(&mut self, runner: F) -> R
    where
        Self: Sized,
    { ... }
}

Suspend an arbitrary reference from access.

Provided methods

fn suspend<F: FnOnce() -> R, R>(&mut self, runner: F) -> R where
    Self: Sized, 

Suspend this object and run runner, which by using another data structure can reborrow &mut Self without violating the mutable aliasing rules.

Only the last emitted object can be suspended.

Panics

Panics if the suspended object is not stored in a Node, or if the object is not at the top of the current node stack.

use revent::{Node, Suspend};
let node1 = Node::new(());
let node2 = Node::new(());
node1.emit(|x1| {
    node2.emit(|x2| {
        x1.suspend(|| {}); // Panic, `node2` was last emitted, we can't suspend `x1`, which
        // comes from `node1`.
    });
});
