Struct ProviderStore 

struct ProviderStore {
    entries: Mutex<HashMap<u32, (String, String)>>,
    next_handle: AtomicU32,
}

Tracks all active language provider registrations with their handles.

A registration is added when an extension calls register_*_provider and removed when Disposable::dispose() is called on the returned handle.

Fields

entries: Mutex<HashMap<u32, (String, String)>>

Map from handle → (provider_type, selector) for diagnostics.

next_handle: AtomicU32

Monotonically increasing handle counter.

fn remove(&self, handle: u32)
