Struct ObservabilityContext 

pub struct ObservabilityContext {
    pub trace_id: Option<String>,
    pub span_id: Option<String>,
    pub run_id: Option<String>,
    pub flow_id: Option<String>,
    pub step_id: Option<String>,
}

Observability context for distributed tracing and logging.

Passed with protocol requests to enable trace correlation and structured logging across the Stepflow runtime and component servers.

Fields

trace_id: Option<String>

OpenTelemetry trace ID (128-bit, hex encoded). Present when tracing is enabled.

span_id: Option<String>

OpenTelemetry span ID (64-bit, hex encoded). Component servers should use this as the parent span.

run_id: Option<String>

The ID of the workflow run (UUID). Present for workflow execution requests, absent for discovery.

flow_id: Option<String>

The ID of the flow being executed (SHA-256 blob hash). Present for workflow execution requests, absent for discovery.

step_id: Option<String>

The ID of the step being executed. Present for step-level execution, absent for workflow-level operations.

Trait Implementations

impl Clone for ObservabilityContext

fn clone(&self) -> ObservabilityContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObservabilityContext

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

Formats the value using the given formatter.

impl Default for ObservabilityContext

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ObservabilityContext

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ObservabilityContext

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Message for ObservabilityContext

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

impl PartialEq for ObservabilityContext

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
