Module trace 

The span line document, rustev.trace/1 (spec 028, 3.10.1): one compact JSON object per span per line, keys sorted, at most 64 KiB per line.

Each attribute value says how it was produced (allow, digest or truncated); a dropped field is absent and listed in rustev.redaction.withheld. A reader parses a line with TraceLine::parse_line, which applies crate::limits::TRACE_V1 and checks the line’s own invariants.

Structs

TraceAttr

One exported attribute: its value and how it was produced.

TraceEvent

A span event (3.5.5).

TraceLine

One span, one line (3.10.1).

TraceResource

The resource, on the root line only (3.2.4, 3.10.1).

TraceScope

The instrumentation scope (3.2.4).

Enums

Mark

How an exported value was produced (3.10.1).

SpanKind

Span kind (3.5.3).

SpanStatus

Span status (3.5.3). An unresolved, escalated or cancelled decision is an answer, so its root stays unset; only a failed or deadline attempt is error.

TraceLineError

Why a line was refused.

TraceValue

An attribute value: a string, integer, number, boolean or a homogeneous array of one of those (3.10.1).

Constants

The schema string of a span line.
