Variants

Start

A new span has been started, but not entered yet.

Fields

ts: u64

Timestamp

id: u64

Unique id for this span.

parent: Option<u64>

Id of the parent span, if any.

name: Cow<'a, str>

The name of the span.

target: Cow<'a, str>

The target of the span.

values: Vec<(Cow<'a, str>, TraceValue<'a>)>

End

A span has ended. The id might be reused in future.

Fields

ts: u64

Timestamp

id: u64

Unique id for this span. Must be created by a Start event before.

Enter

A span has been entered. This means it is spending CPU time now.

Fields

thread_id: u64

The thread id of the thread that entered the span.

Exit

A span has been exited. This means it is not spending CPU time anymore.

Fields

ts: u64

Timestamp

id: u64

Unique id for this span. Must be entered by a Enter event before.

thread_id: u64

The thread id of the thread that exits the span.

Event
