[−][src]Struct holochain_tracing::Tracer
Tracer.
Methods
impl Tracer
[src]
pub fn new<S>(sampler: S) -> (Tracer, Receiver<FinishedSpan<SpanContextState>>) where
S: Sampler<SpanContextState> + Send + Sync + 'static,
[src]
S: Sampler<SpanContextState> + Send + Sync + 'static,
Makes a new Tracer
instance with an unbounded channel.
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<S>(
sampler: S,
span_tx: Sender<FinishedSpan<SpanContextState>>
) -> Tracer where
S: Sampler<SpanContextState> + Send + Sync + 'static,
[src]
sampler: S,
span_tx: Sender<FinishedSpan<SpanContextState>>
) -> Tracer where
S: Sampler<SpanContextState> + Send + Sync + 'static,
Makes a new Tracer
instance.
pub fn clone_with_sampler<T>(&self, sampler: T) -> Tracer where
T: Sampler<SpanContextState> + Send + Sync + 'static,
[src]
T: Sampler<SpanContextState> + Send + Sync + 'static,
Clone with the given sampler
.
pub fn span<N>(
&self,
operation_name: N
) -> StartSpanOptions<Box<dyn Sampler<SpanContextState> + 'static + Send + Sync>, SpanContextState> where
N: Into<Cow<'static, str>>,
[src]
&self,
operation_name: N
) -> StartSpanOptions<Box<dyn Sampler<SpanContextState> + 'static + Send + Sync>, SpanContextState> where
N: Into<Cow<'static, str>>,
Returns StartSpanOptions
for starting a span which has the name operation_name
.
