Struct TraceContext 

pub struct TraceContext {
    pub version: u8,
    pub trace_id: [u8; 16],
    pub parent_id: [u8; 8],
    pub trace_flags: u8,
}

W3C Trace Context (traceparent header)

Represents distributed trace context passed across service boundaries. Enables Renacer to create syscall spans as children of application spans.

Fields

version: u8

trace_id: [u8; 16]

parent_id: [u8; 8]

trace_flags: u8

Implementations

impl TraceContext

pub fn parse(traceparent: &str) -> Result<Self, TraceContextError>

Parse W3C traceparent string

Format: “00-{trace_id}-{parent_id}-{flags}” Example: “00-0af7651916cd43dd8448eb211c80319c-b7ad6b7169203331-01”

pub fn from_env() -> Option<Self>

Extract trace context from environment variables

Checks TRACEPARENT and OTEL_TRACEPARENT (in that order)

pub fn set_env(&self)

Set trace context as environment variable (Sprint 42: Batuta Integration)

Sets TRACEPARENT for child processes to inherit trace context. This enables distributed tracing across exec() boundaries.

pub fn logical_clock_from_env() -> Option<u64>

Extract logical clock from environment variable (Sprint 42: Batuta Integration)

Checks RENACER_LOGICAL_CLOCK environment variable. Returns None if not set or invalid format.

pub fn set_logical_clock_env(timestamp: u64)

Set logical clock as environment variable (Sprint 42: Batuta Integration)

Sets RENACER_LOGICAL_CLOCK for child processes to inherit. This propagates Lamport logical clocks across exec() boundaries.

pub fn is_sampled(&self) -> bool

Check if trace is sampled (trace_flags & 0x01)

Trait Implementations

impl Clone for TraceContext

fn clone(&self) -> TraceContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TraceContext

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

Formats the value using the given formatter.

impl Display for TraceContext

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

Formats the value using the given formatter.

impl PartialEq for TraceContext

fn eq(&self, other: &TraceContext) -> 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.
