Struct mick_jaeger::Span

pub struct Span { /* private fields */ }

Implementations

impl Span

pub fn child(&self, operation_name: impl Into<String>) -> Span

Creates a new Span, child of this one.

Note: There is no need to keep the parent Span alive while the children is alive. The protocol allows for parents that don’t completely overlap their children.

pub fn child_with_id( &self, span_id: NonZeroU64, operation_name: impl Into<String> ) -> Span

Creates a new Span, child of this one, with a specific ID.

pub fn trace_id(&self) -> NonZeroU128

Returns the trace ID originally passed when building this span.

pub fn span_id(&self) -> NonZeroU64

Returns the span ID originally passed when building this span.

pub fn log(&mut self) -> Log<'_>

Add a log entry to this span.

pub fn add_follows_from(&mut self, other: &Span)

Adds a “followfrom” relation ship towards another span of (potentially) another trace.

pub fn add_follows_from_raw( &mut self, trace_id: NonZeroU128, span_id: NonZeroU64 )

Adds a “followfrom” relation ship towards another span of (potentially) another trace.

pub fn add_string_tag(&mut self, key: &str, value: &str)

Add a new key-value tag to this span.

pub fn add_int_tag(&mut self, key: &str, value: i64)

Add a new key-value tag to this span.

pub fn override_start_time(&mut self, start_time: StartTime)

Modifies the start time of this span.

Note: This method can be useful in order to generate a span with a trace_id that is only know after the span should have started. To do so, call StartTime::now when the span should start, create the span once you know the ̀trace_id, then call this method.

pub fn with_start_time_override(self, start_time: StartTime) -> Self

Modifies the start time of this span.

Note: This method can be useful in order to generate a span with a trace_id that is only know after the span should have started. To do so, call StartTime::now when the span should start, create the span once you know the ̀trace_id, then call this method.

Trait Implementations

impl Drop for Span

fn drop(&mut self)

Executes the destructor for this type.
