Enum SpanKind 

pub enum SpanKind {
    Internal,
    Server,
    Client,
    Producer,
    Consumer,
    Unknown(String),
}

The kind of a span.

This corresponds to OTEL’s kind enum, plus a catchall variant for forward compatibility.

Variants

Internal

An operation internal to an application.

Server

Server-side processing requested by a client.

Client

A request from a client to a server.

Producer

Scheduling of an operation.

Consumer

Processing of a scheduled operation.

Unknown(String)

Unknown kind, for forward compatibility.

Implementations

impl SpanKind

pub fn as_str(&self) -> &str

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() -> SpanKind

Returns the “default value” for a type.

impl Display for SpanKind

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

Formats the value using the given formatter.

impl Empty for SpanKind

fn is_empty(&self) -> bool

Returns whether this value is empty.

fn is_deep_empty(&self) -> bool

Returns whether this value is empty or all of its descendants are empty.

impl FromStr for SpanKind

type Err = ParseSpanKindError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl FromValue for SpanKind

fn from_value(value: Annotated<Value>) -> Annotated<Self>

where Self: Sized,

Creates a meta structure from an annotated boxed value.

impl IntoValue for SpanKind

fn into_value(self) -> Value

where Self: Sized,

Boxes the meta structure back into a value.

fn serialize_payload<S>( &self, s: S, _behavior: SkipSerialization, ) -> Result<S::Ok, S::Error>

where Self: Sized, S: Serializer,

Efficiently serializes the payload directly.

fn extract_child_meta(&self) -> BTreeMap<String, MetaTree>

where Self: Sized,

Extracts children meta map out of a value.

fn extract_meta_tree(value: &Annotated<Self>) -> MetaTree

where Self: Sized,

Extracts the meta tree out of annotated value.

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 ProcessValue for SpanKind

fn value_type(&self) -> EnumSet<ValueType>

Returns the type of the value.

fn process_value<P>( &mut self, __meta: &mut Meta, __processor: &mut P, __state: &ProcessingState<'_>, ) -> ProcessingResult

where P: Processor,

Executes a processor on this value.

fn process_child_values<P>( &mut self, __processor: &mut P, __state: &ProcessingState<'_>, ) -> ProcessingResult

where P: Processor,

Recurses into children of this value.
