Struct rustracing::span::Span [−][src]
pub struct Span<T>(_);
Span.
When this span is dropped, it will be converted to FinishedSpan and
it will be sent to the associated SpanReceiver.
Methods
impl<T> Span<T>[src]
impl<T> Span<T>pub fn inactive() -> Self[src]
pub fn inactive() -> SelfMakes an inactive span.
This span is never traced.
Examples
use rustracing::span::Span; let span = Span::<()>::inactive(); assert!(! span.is_sampled());
pub fn handle(&self) -> SpanHandle<T> where
T: Clone, [src]
pub fn handle(&self) -> SpanHandle<T> where
T: Clone, Returns a handle of this span.
pub fn is_sampled(&self) -> bool[src]
pub fn is_sampled(&self) -> boolReturns true if this span is sampled (i.e., being traced).
pub fn context(&self) -> Option<&SpanContext<T>>[src]
pub fn context(&self) -> Option<&SpanContext<T>>Returns the context of this span.
pub fn set_operation_name<F, N>(&mut self, f: F) where
F: FnOnce() -> N,
N: Into<Cow<'static, str>>, [src]
pub fn set_operation_name<F, N>(&mut self, f: F) where
F: FnOnce() -> N,
N: Into<Cow<'static, str>>, Sets the operation name of this span.
pub fn set_finish_time<F>(&mut self, f: F) where
F: FnOnce() -> SystemTime, [src]
pub fn set_finish_time<F>(&mut self, f: F) where
F: FnOnce() -> SystemTime, Sets the finish time of this span.
pub fn set_tag<F>(&mut self, f: F) where
F: FnOnce() -> Tag, [src]
pub fn set_tag<F>(&mut self, f: F) where
F: FnOnce() -> Tag, Sets the tag to this span.
Sets the tags to this span.
pub fn set_baggage_item<F>(&mut self, f: F) where
F: FnOnce() -> BaggageItem, [src]
pub fn set_baggage_item<F>(&mut self, f: F) where
F: FnOnce() -> BaggageItem, Sets the baggage item to this span.
pub fn get_baggage_item(&self, name: &str) -> Option<&BaggageItem>[src]
pub fn get_baggage_item(&self, name: &str) -> Option<&BaggageItem>Gets the baggage item that has the name name.
pub fn log<F>(&mut self, f: F) where
F: FnOnce(&mut LogBuilder), [src]
pub fn log<F>(&mut self, f: F) where
F: FnOnce(&mut LogBuilder), Logs structured data.
pub fn error_log<F>(&mut self, f: F) where
F: FnOnce(&mut StdErrorLogFieldsBuilder), [src]
pub fn error_log<F>(&mut self, f: F) where
F: FnOnce(&mut StdErrorLogFieldsBuilder), Logs an error.
This is a simple wrapper of log method
except that the StdTag::error() tag will be set in this method.
pub fn child<N, F>(&self, operation_name: N, f: F) -> Span<T> where
N: Into<Cow<'static, str>>,
T: Clone,
F: FnOnce(StartSpanOptions<AllSampler, T>) -> Span<T>, [src]
pub fn child<N, F>(&self, operation_name: N, f: F) -> Span<T> where
N: Into<Cow<'static, str>>,
T: Clone,
F: FnOnce(StartSpanOptions<AllSampler, T>) -> Span<T>, Starts a ChildOf span if this span is sampled.
pub fn follower<N, F>(&self, operation_name: N, f: F) -> Span<T> where
N: Into<Cow<'static, str>>,
T: Clone,
F: FnOnce(StartSpanOptions<AllSampler, T>) -> Span<T>, [src]
pub fn follower<N, F>(&self, operation_name: N, f: F) -> Span<T> where
N: Into<Cow<'static, str>>,
T: Clone,
F: FnOnce(StartSpanOptions<AllSampler, T>) -> Span<T>, Starts a FollowsFrom span if this span is sampled.
