Implementations

impl Span

pub fn new( trace_id: impl Into<String>, span_id: impl Into<String>, name: impl Into<String>, start_time: i64, end_time: i64, ) -> Self

Create a new span

pub fn with_parent(self, parent_span_id: impl Into<String>) -> Self

Set the parent span ID

pub fn with_kind(self, kind: SpanKind) -> Self

Set the span kind

pub fn with_attribute( self, key: impl Into<String>, value: impl Into<String>, ) -> Self

Add an attribute to the span

pub fn with_event(self, event: SpanEvent) -> Self

Add an event to the span

pub fn with_status(self, code: StatusCode, message: Option<String>) -> Self

Set the span status

pub fn duration_ns(&self) -> i64

Calculate span duration in nanoseconds

Trait Implementations

impl Clone for Span

fn clone(&self) -> Span

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Span

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Span

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Span> for SpanEntry

fn from(span: Span) -> Self

Converts to this type from the input type.

impl PartialEq for Span

fn eq(&self, other: &Span) -> 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.

impl Serialize for Span

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
