Struct Fuse 

pub struct Fuse<T: LinkReference, H: FnMut(Link<T>, Link<T>) -> Flow> { /* private fields */ }

A write-handler wrapper that stops calling the inner handler once it returns Flow::Break.

After the first Break, every subsequent call to Fuse::call also returns Break without invoking the wrapped closure.

Implementations

impl<T: LinkReference, F: FnMut(Link<T>, Link<T>) -> Flow> Fuse<T, F>

pub fn new(handler: F) -> Self

Wraps handler in a Fuse.

pub fn call(&mut self, before: Link<T>, after: Link<T>) -> Flow

Calls the inner handler unless it has already returned Flow::Break.
