Struct Extensions 

Source 
pub struct Extensions { /* private fields */ }
Expand description

Registry of (Protocol, Interpret) pairs by namespace, plus the router-internal Core. Cheaply cloneable and shared (interior mutability) so the Provider and the inbound callback see the same table.

Implementations§

Source§

impl Extensions

Source

pub fn new(processor: Arc<Processor>) -> Self

Empty registry over a processor (the source of overlay send / did).

Source

pub fn register<P, I>(&self, protocol: P, interpret: I) -> Result<()>
where P: Protocol + MaybeSend + 'static, P::State: MaybeSend + 'static, P::Effect: MaybeSend, I: Interpret<Effect = P::Effect> + MaybeSend + 'static,

Register a protocol together with its interpreter under the protocol’s namespace. Errors if the namespace is already taken — use replace for intentional replacement (no more silent overwrite).

Source

pub fn replace<P, I>(&self, protocol: P, interpret: I) -> Result<()>
where P: Protocol + MaybeSend + 'static, P::State: MaybeSend + 'static, P::Effect: MaybeSend, I: Interpret<Effect = P::Effect> + MaybeSend + 'static,

Like register but replaces an existing protocol on the same namespace instead of erroring. For deliberate hot-swaps.

Source

pub fn register_many<P, I>(&self, items: Vec<(P, I)>) -> Result<()>
where P: Protocol + MaybeSend + 'static, P::State: MaybeSend + 'static, P::Effect: MaybeSend, I: Interpret<Effect = P::Effect> + MaybeSend + 'static,

Register several protocols atomically: build every runner, then under a single write lock verify that none of their namespaces is taken (by an existing registration or by a duplicate within the batch) and insert them all — or change nothing and return Err. The pairs share the type P/I (e.g. the relay’s TCP + UDP Relay<T> instances), so a partial install can never leave one namespace claimed while the caller gets no handle.

Source

pub fn contains(&self, namespace: &str) -> bool

Whether a namespace is registered.
