[−][src]Trait opentelemetry::sdk::trace::ShouldSample

pub trait ShouldSample: Send + Sync + Debug {
    fn should_sample(
        &self, 
        parent_context: Option<&SpanReference>, 
        trace_id: TraceId, 
        name: &str, 
        span_kind: &SpanKind, 
        attributes: &[KeyValue], 
        links: &[Link]
    ) -> SamplingResult;
}

The ShouldSample interface allows implementations to provide samplers which will return a sampling SamplingResult based on information that is typically available just before the Span was created.

Required methods

`fn should_sample( &self, parent_context: Option<&SpanReference>, trace_id: TraceId, name: &str, span_kind: &SpanKind, attributes: &[KeyValue], links: &[Link] ) -> SamplingResult`

Returns the SamplingDecision for a Span to be created.
