Struct RiTraceContext 

pub struct RiTraceContext {
    pub version: u8,
    pub trace_id: RiTraceId,
    pub parent_id: RiSpanId,
    pub trace_flags: u8,
    pub trace_state: Option<String>,
}

W3C Trace Context propagation format

This struct represents a W3C Trace Context, which is used to propagate trace information across service boundaries. It follows the W3C Trace Context specification: https://www.w3.org/TR/trace-context/

Fields

version: u8

Trace context version

trace_id: RiTraceId

Trace ID for the entire trace

parent_id: RiSpanId

Parent span ID

trace_flags: u8

Trace flags (bitmask)

trace_state: Option<String>

Optional trace state for vendor-specific information

Implementations

impl RiTraceContext

pub fn new(trace_id: RiTraceId, parent_id: RiSpanId) -> Self

Creates a new trace context with the given trace ID and parent span ID.

Parameters

• trace_id: The trace ID for the trace
• parent_id: The parent span ID

Returns

A new RiTraceContext instance

pub fn from_header(header: &str) -> Option<Self>

Parses a trace context from a W3C Trace Context header string.

Parameters

• header: The traceparent header string in format “00-{trace-id}-{parent-id}-{trace-flags}”

Returns

An Option containing the parsed RiTraceContext, or None if parsing failed

pub fn to_header(&self) -> String

Converts the trace context to a W3C Trace Context header string.

Returns

A string in the format “00-{trace-id}-{parent-id}-{trace-flags}”

pub fn is_sampled(&self) -> bool

Checks if the trace is sampled.

Returns

True if the sampled flag is set, false otherwise

pub fn set_sampled(&mut self, sampled: bool)

Sets the sampled flag on the trace context.

Parameters

• sampled: Whether the trace should be sampled

const RAW_DOC: &'static CStr = c"W3C Trace Context propagation format\n\nThis struct represents a W3C Trace Context, which is used to propagate trace information\nacross service boundaries. It follows the W3C Trace Context specification: https://www.w3.org/TR/trace-context/\x00"

Docstring for the class provided on the struct or enum.

const DOC: &'static CStr

Base class

type ThreadChecker = SendablePyClass<RiTraceContext>

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild
