Enum SpanKind 

pub enum SpanKind {
    Internal,
    Server,
    Client,
    Producer,
    Consumer,
}

OpenTelemetry-aligned span kind. Mirrors opentelemetry::trace::SpanKind without depending on it. Used by backends to colour spans in the UI and to apply kind-specific semantic conventions.

Variants

Internal

Default. Internal operation within an application.

Server

An incoming request the application is handling.

Client

An outgoing request to another service.

Producer

Async producer (e.g. enqueue a message).

Consumer

Async consumer (e.g. process a message from a queue).

Trait Implementations

impl Clone for SpanKind

fn clone(&self) -> SpanKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpanKind

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

Formats the value using the given formatter.

impl Default for SpanKind

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SpanKind

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SpanKind

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
