Struct RequestTrace 

pub struct RequestTrace { /* private fields */ }

The accumulated causal trace for one request, filled stage by stage.

Constructed with the RequestId and populated via the record_* setters; assembled into a /debug/explain document by crate::explain_json.

Implementations

impl RequestTrace

pub fn new() -> Self

A new, empty trace.

pub fn record_context(&mut self, context: TraceContext)

Records the request’s W3C trace context (trace/span ids).

pub fn context(&self) -> Option<&TraceContext>

The request’s trace context, once recorded.

pub fn resolved_partition(&self) -> Option<&PartitionId>

The partition the request resolved to, once routing has run, so a tenant-targeted diagnostics directive can be evaluated against it.

pub fn record_ingress(&mut self, info: IngressInfo)

Records the ingress span.

pub fn record_classify(&mut self, info: ClassifyInfo)

Records the classify span.

pub fn record_resolve(&mut self, info: ResolveInfo)

Records the spi.resolve span.

pub fn record_rewrite(&mut self, info: RewriteInfo)

Records the rewrite span.

pub fn record_dispatch(&mut self, info: DispatchInfo)

Records the dispatch span.

pub fn record_egress(&mut self, info: EgressInfo)

Records the egress span.

pub fn record_error(&mut self, error: ErrorContext)

Attaches the error context to the failing span.

pub fn failed(&self) -> bool

Whether the request failed (carries an error context).

Trait Implementations

impl Clone for RequestTrace

fn clone(&self) -> RequestTrace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RequestTrace

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

Formats the value using the given formatter.

impl Default for RequestTrace

fn default() -> RequestTrace

Returns the “default value” for a type.

impl Eq for RequestTrace

impl PartialEq for RequestTrace

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