fastrace-macro

• Upgrade syn to 3.

Notable Changes

• Upgraded MSRV to 1.91.

Breaking Changes

• Deprecated Span::enter_with_parents(). It now uses the first non-noop parent as the primary parent and converts additional parents to links.

New Features

• Added Span::with_link() and Span::add_link().
• Added LocalSpan::with_link() and LocalSpan::add_link().
• Added SpanRecord.links and propagated links through collector post-processing.
• Added serde::Serialize and serde::Deserialize support for SpanContext using W3C traceparent format.

Bug Fixes

• Fixed #[trace] macro span attachment by generating the wrapper function with the original function span.

Improvements

• Deprecated Config::tail_sampled().
• Spans are held until the root span finishes by default, and Span::cancel() discards spans collected up to the root span drop.

Bug Fixes

• #[trace] macro now supports trait-object futures and preserves input tokens more faithfully to avoid compilation errors.

Improvements

• Added #[allow(unreachable_code)] on the macro return hint to quiet new compiler warnings.

fix: stale spans not being cleared after reporting (#123)

Bug Fixes

• Fixed stale spans not being cleared after reporting.

chore: release v0.1.13 (#121)

Bug Fixes

• Propagated trace context no matter whether the reporter is set.
• Fixed an issue where SpanContext::random() returned a non-zero parent id.

New Features

• TraceContext::random() now returns a TraceContext with random TraceId and SpanId.
• Added Config::tail_sampled(), which defaults to false.
• Added attribute #[trace(crate = ::fastrace)] to redirect the path to the fastrace crate.

Improvements

• Deprecated Config::max_spans_per_trace() and Config::report_before_root_finish().

Breaking Changes

• Upgraded MSRV to 1.80.

Improvements

• Improved performance.

New Features

• Added TraceId::random() and SpanId::random().
• Added FromStr, Display, and serde support for TraceId and SpanId.
• Added Span::add_property() and Span::add_properties().
• Added Span::add_event() and LocalSpan::add_event().

Improvements

• Deprecated Event::add_to_parent() and Event::add_to_local_parent().

• Reduced dependencies to futures 0.3.

Improvements

• Optimized collect behavior when the span is not sampled.

Improvements

Improvements

• Upgraded opentelemetry to 0.25.0.

New Features
