Struct TraceBufferHandle 

pub struct TraceBufferHandle { /* private fields */ }

Thread-safe handle for sharing a trace buffer across tasks.

This wraps a TraceBuffer in a mutex and adds a monotonically increasing sequence counter for event ordering.

Implementations

impl TraceBufferHandle

pub fn new(capacity: usize) -> Self

Creates a new trace buffer handle with the given capacity.

pub fn next_seq(&self) -> u64

Allocates and returns the next trace sequence number.

pub fn push_event(&self, event: TraceEvent)

Pushes a trace event into the buffer.

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

Returns a snapshot of buffered events in order (oldest to newest).

pub fn len(&self) -> usize

Returns the current number of buffered events.

pub fn is_empty(&self) -> bool

Returns true if the buffer is empty.
