Struct ContextSourceRegistry 

pub struct ContextSourceRegistry { /* private fields */ }

Runtime-mutable registry of AsyncContextSources.

The plugin loader RCU-registers a loaded context plugin’s producer here (drain_context); the host’s reparse-driven refresh reads a wait-free snapshot to drive them. Named generically (not Wasm…) because it holds native trait objects — the WASM source is one implementor among potential natives, exactly as with GutterDecorationSourceRegistry.

Implementations

impl ContextSourceRegistry

pub fn new() -> Self

An empty registry.

pub fn register(&mut self, source: Arc<dyn AsyncContextSource>)

Register a producer. Idempotent per source_id: a re-register (reload) replaces the prior producer for that id rather than accumulating a duplicate.

pub fn unregister(&mut self, source_id: u64) -> usize

Unregister every producer for source_id; returns the count removed (the teardown-report increment). No-op when absent — idempotent, per the teardown contract.

pub fn sources(&self) -> Vec<Arc<dyn AsyncContextSource>>

A wait-free snapshot of the registered producers (cheap Arc clones) — what the host’s refresh iterates.

pub fn is_empty(&self) -> bool

True when no producer is registered.

pub fn len(&self) -> usize

Number of registered producers.
