Required Methods

fn remove(&self, identifier: &TransferFrameID) -> Option<F>

Remove and return the next frame matching the indentifier if such frame exist.

It's important that receive returns frames in the correct order.

fn find_id<P>(&self, predicate: P) -> Option<FullTransferID> where
    P: FnMut(&F) -> bool, 

Finds the first element matching the predicate and returns its TransferFrameID.

fn retain<P>(&self, predicate: P) where
    P: FnMut(&F) -> bool, 

Retains only the elements specified by the predicate.

In other words, remove all elements e such that f(&e) returns false. This method must operate in place and preserves the order of the retained elements.
