package tracing

import "github.com/open-policy-agent/opa/tracing"

Deprecated: This package is intended for older projects transitioning from OPA v0.x and will remain for the lifetime of OPA v1.x, but its use is not recommended. For newer features and behaviours, such as defaulting to the Rego v1 syntax, use the corresponding components in the github.com/open-policy-agent/opa/v1 package instead. See https://www.openpolicyagent.org/docs/latest/v0-compatibility/ for more information.

Package tracing enables dependency-injection at runtime. When used together with an underscore-import of `github.com/open-policy-agent/opa/features/tracing`, the server and its runtime will emit OpenTelemetry spans to the configured sink.
