Struct RecordingSink 

pub struct RecordingSink { /* private fields */ }

A simple recording sink that accumulates events in insertion order.

Backed by a Mutex<Vec<TraceEvent>> so the sink is Send + Sync and can be shared across threads via Arc<RecordingSink> and installed through with_global_sink / set_global_sink. The single-thread Rc<RecordingSink> path through with_sink continues to work and pays only the Mutex acquisition cost when an event is recorded (still zero-cost when no sink is installed).

Implementations

impl RecordingSink

pub fn new() -> Self

Create a fresh recording sink.

pub fn events(&self) -> Vec<TraceEvent>

Snapshot the recorded events.

pub fn len(&self) -> usize

Number of events recorded so far.

pub fn is_empty(&self) -> bool

Whether no events have been recorded.

pub fn to_canonical_json(&self) -> String

Render all events to canonical JSON.

Trait Implementations

impl Debug for RecordingSink

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RecordingSink

fn default() -> RecordingSink

Returns the “default value” for a type.

impl Sink for RecordingSink

fn record(&self, event: TraceEvent)

Receive a single event. Implementations should not perform I/O or take locks that risk contention with engine work.
