Struct DiagnosticSink 

pub struct DiagnosticSink { /* private fields */ }

Thread-safe sink for Diagnostic events keyed by DiagnosticKey. Uses BTreeMap so iteration order is deterministic (driven by DiagnosticKey’s Ord) independent of insertion order. First writer per key wins; canonicalisation at insertion time means payloads for the same key are identical by construction.

Implementations

impl DiagnosticSink

pub fn new() -> DiagnosticSink

Creates an empty deterministic diagnostic sink.

pub fn push(&self, diagnostic: Diagnostic)

Insert a diagnostic if no diagnostic with the same key has been inserted yet. Canonicalises the payload before insertion so later equality checks are stable.

pub fn for_each<F>(&self, f: F)

where F: FnMut(&Diagnostic),

Run a closure over the BTreeMap iterator. Held under the mutex for the duration of the closure; keep it short.

pub fn snapshot(&self) -> Vec<Diagnostic>

Snapshot the diagnostics as a new Vec. Useful for tests; in hot paths prefer for_each.

pub fn len(&self) -> usize

Number of distinct diagnostic keys currently held.

pub fn is_empty(&self) -> bool

True when no diagnostics have been emitted.
