Summary

Types

traced_fun/1

Callbacks

start_span/4
with_span/5

Functions

current_span_ctx()
current_span_ctx(Ctx)
from_remote_span(TraceId, SpanId, Traceflags)

Returns a span_ctx record with is_recording set to false and is_remote set to true. This is mainly for use in propagators when they extract a Span to be used as a parent.

non_recording_span(TraceId, SpanId, Traceflags)

Returns a span_ctx record with is_recording set to false. This is mainly for use in propagators when they extract a Span to be used as a parent.
