Name: opentelemetry-rust

Owner: OpenTelemetry - CNCF

Release: v0.5.0

Released: 2020-05-10

License: Apache-2.0

Release Assets:

Added

  • Derive Clone for B3Propagator, SamplingResult, and SpanBuilder
  • Ability to configure the span id / trace id generator
  • impl From<T> for common Key and Value types
  • Add global tracer method
  • Add Resource API
  • Add Context API
  • Add Correlations API
  • Add HttpTextCompositePropagator for composing HttpTextPropagators
  • Add GlobalPropagator for globally configuring a propagator
  • Add TraceContextExt to provide methods for working with trace data in a context
  • Expose EvictedQueue constructor

Changed

  • Ensure that impls of Span are Send and Sync when used in global
  • Changed Key and Value method signatures to remove Cow references
  • Tracer's start now uses the implicit current context instead of an explicit span context. start_with_context may be used to specify a context if desired.
  • with_span now accepts a span for naming consistency and managing the active state of a more complex span (likely produced by a builder), and the previous functionality that accepts a &str has been renamed to in_span, both of which now yield a context to the provided closure.
  • Tracer's get_active_span now accepts a closure
  • The Instrument trait has been renamed to FutureExt to avoid clashing with metric instruments, and instead accepts contexts via with_context.
  • Span's get_context method has been renamed to span_context to avoid ambiguity.
  • HttpTextPropagators inject the current context instead of an explicit span context. The context can be specified with inject_context.
  • SpanData's context has been renamed to span_context

Fixed

  • Update the probability sampler to match the spec
  • Rename Traceparent header to traceparent

Removed

  • TracerGenerics methods have been folded in to the Tracer trait so it is longer needed
  • Tracer's mark_span_as_inactive has been removed
  • Exporters no longer require an as_any method
  • Span's mark_as_active, mark_as_inactive, and as_any have been removed
