Struct DispatchTrace 

pub struct DispatchTrace { /* private fields */ }

Append-only collector for DispatchTraceEvent values.

Clones share the same underlying buffer (Arc + Mutex), so a trace handed to the dispatcher and a trace inspected by the host see the same events.

Implementations

impl DispatchTrace

pub fn new() -> Self

Create an empty trace.

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

Snapshot the events recorded so far.

pub fn len(&self) -> usize

Number of recorded events.

pub fn is_empty(&self) -> bool

Whether no events have been recorded.
