Enum SpanKind 

pub enum SpanKind {
    Internal = 1,
    Server = 2,
    Client = 3,
}

OTLP SpanKind. Numbering matches the OTLP spec (INTERNAL=1, SERVER=2, CLIENT=3) so the numeric value can be cast directly with as i32 when building OTLP JSON. PRODUCER/CONSUMER are intentionally not exposed — nothing in this crate does message-queue instrumentation yet.

Variants

Internal = 1

Internal work with no remote counterpart — DB query, cache lookup, business logic. The default for span.

Server = 2

The span created by OtelLayer for an incoming HTTP request.

Client = 3

An outbound call to another service. The kind for client_span.

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 Copy for SpanKind

impl Debug for SpanKind

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

Formats the value using the given formatter.

impl Default for SpanKind

fn default() -> SpanKind

Returns the “default value” for a type.

impl Eq for SpanKind

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.
