Struct TraceOverheadReport 

pub(crate) struct TraceOverheadReport {
    pub(crate) benchmark: &'static str,
    pub(crate) backend: Backend,
    pub(crate) untraced_wall_ns: u64,
    pub(crate) traced_wall_ns: u64,
    pub(crate) overhead_ratio: f64,
}

Compares one benchmark run untraced against the same run under a real JsonlSink writing nowhere: the difference is tracing’s own cost, not the cost of whatever the sink’s destination happens to be.

Fields

benchmark: &'static str

backend: Backend

untraced_wall_ns: u64

traced_wall_ns: u64

overhead_ratio: f64
