Struct TraceContext 

pub struct TraceContext {
    pub trace_id: TraceId,
    pub span_id: SpanId,
}

W3C Trace Context carried through a flow for distributed tracing.

Combines a trace ID and span ID. Propagated through flow-context resources in the WIT layer.

Examples

use torvyn_types::{TraceContext, TraceId, SpanId};

let ctx = TraceContext::new(
    TraceId::new([1; 16]),
    SpanId::new([2; 8]),
);
assert!(ctx.is_valid());

Fields

trace_id: TraceId

The W3C trace ID (128-bit).

span_id: SpanId

The W3C span ID (64-bit) for the current scope.

Implementations

impl TraceContext

pub const fn new(trace_id: TraceId, span_id: SpanId) -> Self

Create a new TraceContext.

COLD PATH — created at flow start or when entering a new span.

pub fn is_valid(&self) -> bool

Returns true if both trace ID and span ID are valid (non-zero).

pub const fn disabled() -> Self

Returns an invalid context (tracing disabled).

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<'de> Deserialize<'de> for TraceContext

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TraceContext

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

Formats the value using the given formatter.

impl Hash for TraceContext

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 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.

impl Serialize for TraceContext

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for TraceContext

impl Eq for TraceContext
