pub fn get(&self, c: Channel) -> Option<&T>

The value of a channel, or None when the handle is stale.

pub fn get_mut(&mut self, c: Channel) -> Option<&mut T>

The value of a channel, to change it, or None when the handle is stale.

pub fn remove(&mut self, c: Channel) -> Option<T>

Free a channel and return its value.

pub fn iter(&self) -> impl Iterator<Item = (Channel, &T)>

The channels in use, with their values.

pub fn len(&self) -> usize

The number of channels in use.

pub fn is_empty(&self) -> bool

Whether no channel is in use.
