Struct SpanContext

#[non_exhaustive]
pub struct SpanContext {
    pub span_name: String,
}

The context of a span. This is attached to an Exemplar in Distribution values during aggregation.

It contains the name of a span with format:

projects/[PROJECT_ID_OR_NUMBER]/traces/[TRACE_ID]/spans/[SPAN_ID]

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

span_name: String

The resource name of the span. The format is:

projects/[PROJECT_ID_OR_NUMBER]/traces/[TRACE_ID]/spans/[SPAN_ID]

[TRACE_ID] is a unique identifier for a trace within a project; it is a 32-character hexadecimal encoding of a 16-byte array.

[SPAN_ID] is a unique identifier for a span within a trace; it is a 16-character hexadecimal encoding of an 8-byte array.

Implementations

impl SpanContext

pub fn set_span_name<T: Into<String>>(self, v: T) -> Self

Sets the value of span_name.

Trait Implementations

impl Clone for SpanContext

fn clone(&self) -> SpanContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SpanContext

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

Formats the value using the given formatter.

impl Default for SpanContext

fn default() -> SpanContext

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SpanContext

where SpanContext: Default,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for SpanContext

fn typename() -> &'static str

The typename of this message.

impl PartialEq for SpanContext

fn eq(&self, other: &SpanContext) -> 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 SpanContext

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
