enum Sampler {
AlwaysOn,
AlwaysOff,
TraceIdRatio(f64),
}Expand description
New-trace sampling strategy (used only when no incoming traceparent).

Source§impl Sampler
impl Sampler
Sourcefn sample_new(&self, trace_id: &str) -> bool
fn sample_new(&self, trace_id: &str) -> bool
Decides whether a brand-new trace should be sampled.
always_on/always_off are unconditional; trace_id_ratio compares a
pseudo-random, per-trace-consistent draw derived from trace_id against
the fraction (see ratio_draw).
