Module: OpenTelemetry::Trace::SpanKind

Defined in:: lib/opentelemetry/trace/span_kind.rb

Overview

Type of span. Can be used to specify additional relationships between spans in addition to a parent/child relationship. For API ergonomics, use of the symbols rather than the constants may be preferred. For example:

span = tracer.start_span('op', kind: :client)
