Enum SpanKind 

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

Span kind, aligned with OTel SpanKind.

Variants

Server

Synchronous remote call receiver.

Client

Synchronous remote call sender.

Producer

Asynchronous message sender.

Consumer

Asynchronous message receiver.

Internal

In-process operation.

Implementations

impl SpanKind

pub fn parse(s: &str) -> Self

Parse a span kind string (case-insensitive).

Backends use different casing conventions — OTel-based stores typically use "Client" / "Server", while Jaeger uses lowercase "client" / "server". This method normalises them all.

Unknown or empty values map to SpanKind::Internal.

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<'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.
