[−][src]Struct rustracing::Tracer
Tracer.
Examples
use rustracing::Tracer; use rustracing::sampler::AllSampler; let (span_tx, span_rx) = crossbeam_channel::bounded(10); let tracer = Tracer::with_sender(AllSampler, span_tx); { let _span = tracer.span("foo").start_with_state(()); } let span = span_rx.try_recv().unwrap(); assert_eq!(span.operation_name(), "foo");
Methods
impl<S: Sampler<T>, T> Tracer<S, T>
[src]
pub fn new(sampler: S) -> (Self, SpanReceiver<T>)
[src]
This constructor is mainly for backward compatibility, it has the same interface
as in previous versions except the type of SpanReceiver
.
It builds an unbounded channel which may cause memory issues if there is no reader,
prefer with_sender()
alternative with a bounded one.
pub fn with_sender(sampler: S, span_tx: SpanSender<T>) -> Self
[src]
Makes a new Tracer
instance.
pub fn span<N>(&self, operation_name: N) -> StartSpanOptions<S, T> where
N: Into<Cow<'static, str>>,
[src]
N: Into<Cow<'static, str>>,
Returns StartSpanOptions
for starting a span which has the name operation_name
.
impl<S, T> Tracer<S, T>
[src]
pub fn clone_with_sampler<U: Sampler<T>>(&self, sampler: U) -> Tracer<U, T>
[src]
Clone with the given sampler
.
