Struct SpanLink 

pub struct SpanLink { /* private fields */ }

A link between spans describing a causal relationship.

Implementations

impl SpanLink

pub fn new(trace_id: u64, span_id: u64) -> Self

Creates a new span link for the provided identifiers.

pub fn with_trace_id(self, trace_id: u64) -> Self

Sets the trace identifier.

pub fn with_trace_id_high(self, trace_id_high: u64) -> Self

Sets the high bits of the trace identifier.

pub fn with_span_id(self, span_id: u64) -> Self

Sets the span identifier.

pub fn with_attributes( self, attributes: impl Into<Option<FastHashMap<MetaString, MetaString>>>, ) -> Self

Replaces the attributes map.

pub fn with_tracestate(self, tracestate: impl Into<MetaString>) -> Self

Sets the W3C tracestate value.

pub fn with_flags(self, flags: u32) -> Self

Sets the W3C trace flags.

pub fn trace_id(&self) -> u64

Returns the trace identifier.

pub fn trace_id_high(&self) -> u64

Returns the high bits of the trace identifier.

pub fn span_id(&self) -> u64

Returns the span identifier.

pub fn attributes(&self) -> &FastHashMap<MetaString, MetaString>

Returns the attributes map.

pub fn tracestate(&self) -> &str

Returns the W3C tracestate value.

pub fn flags(&self) -> u32

Returns the W3C trace flags.

Trait Implementations

impl Clone for SpanLink

fn clone(&self) -> SpanLink

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SpanLink

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SpanLink

fn default() -> SpanLink

Returns the “default value” for a type.

impl PartialEq for SpanLink

fn eq(&self, other: &SpanLink) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
