[src]fn invalid(&self) -> Self::Span
[src]
fn invalid(&self) -> Self::Span
[src]Returns a span with an inactive SpanContext
. Used by functions that
need to return a default span like get_active_span
if no span is present.
fn start_with_context<T>(&self, name: T, cx: Context) -> Self::Span where
T: Into<Cow<'static, str>>,
[src]
fn start_with_context<T>(&self, name: T, cx: Context) -> Self::Span where
T: Into<Cow<'static, str>>,
[src]Starts a new Span
with a given context.
Each span has zero or one parent spans and zero or more child spans, which represent causally related operations. A tree of related spans comprises a trace. A span is said to be a root span if it does not have a parent. Each trace includes a single root span, which is the shared ancestor of all other spans in the trace.
fn span_builder<T>(&self, name: T) -> SpanBuilder where
T: Into<Cow<'static, str>>,
[src]
fn span_builder<T>(&self, name: T) -> SpanBuilder where
T: Into<Cow<'static, str>>,
[src]Creates a span builder
An ergonomic way for attributes to be configured before the Span
is started.
fn build(&self, builder: SpanBuilder) -> Self::Span
[src]
fn build(&self, builder: SpanBuilder) -> Self::Span
[src]Starts a span from a SpanBuilder
.
Each span has zero or one parent spans and zero or more child spans, which represent causally related operations. A tree of related spans comprises a trace. A span is said to be a root span if it does not have a parent. Each trace includes a single root span, which is the shared ancestor of all other spans in the trace.
fn start<T>(&self, name: T) -> Self::Span where
T: Into<Cow<'static, str>>,
[src]
fn start<T>(&self, name: T) -> Self::Span where
T: Into<Cow<'static, str>>,
[src]Starts a new Span
