pub struct EventArgRecorder<'p> {
    profiler: &'p SelfProfiler,
    args: SmallVec<[StringId; 2]>,
}
Expand description

A helper for recording costly arguments to self-profiling events. Used with SelfProfilerRef::generic_activity_with_arg_recorder.

Fields§

§profiler: &'p SelfProfiler

The SelfProfiler used to intern the event arguments that users will ask to record.

§args: SmallVec<[StringId; 2]>

The interned event arguments to be recorded in the generic activity event.

The most common case, when actually recording event arguments, is to have one argument. Then followed by recording two, in a couple places.

Implementations§

source§

impl EventArgRecorder<'_>

source

pub fn record_arg<A>(&mut self, event_arg: A)
where A: Borrow<str> + Into<String>,

Records a single argument within the current generic activity being profiled.

Note: when self-profiling with costly event arguments, at least one argument needs to be recorded. A panic will be triggered if that doesn’t happen.
