Struct ChannelRegistry 

pub struct ChannelRegistry { /* private fields */ }

The channels a session can hold a conversation in, and the keys to reach them.

Channel membership already lives in the MAC, which resolves an inbound frame to a key by authenticating it. This is the chat layer’s own view: it maps between the tag a conversation is keyed by and the key a send needs, in both directions.

Implementations

impl ChannelRegistry

pub fn register( &mut self, tag: ChannelTag, key: ChannelKey, max_flood_hops: Option<u8>, )

Hold tag’s channel, reached with key. Registering a held channel again replaces its key and ceiling.

pub fn remove(&mut self, tag: &ChannelTag)

pub fn key(&self, tag: &ChannelTag) -> Option<ChannelKey>

pub fn tag_for(&self, key: &ChannelKey) -> Option<ChannelTag>

The tag of the held channel key reaches.

A received frame names its channel by the key that authenticated it, which is the truth about which channel it belongs to: distinct keys may share the two-byte identifier the frame carried.

pub fn max_flood_hops(&self, tag: &ChannelTag) -> Option<u8>

The flood-hop ceiling registered for a channel, if the user set one. None both for a channel left at the default and for one not registered at all.

pub fn contains(&self, tag: &ChannelTag) -> bool

pub fn tags(&self) -> impl Iterator<Item = ChannelTag> + '_
