0.1.27 (June 7, 2022)

This release of tracing-core introduces a new DefaultCallsite type, which can be used by instrumentation crates rather than implementing their own callsite types. Using DefaultCallsite may offer reduced overhead from callsite registration.

Added

• DefaultCallsite, a pre-written Callsite implementation for use in instrumentation crates (#2083)
• ValueSet::len and Record::len methods returning the number of fields in a ValueSet or Record (#2152)

Changed

• Replaced lazy_static dependency with once_cell (#2147)

Documented

• Added documentation to the callsite module (#2088, #2149)

Thanks to new contributors @jamesmunns and @james7132 for contributing to this release!

0.1.26 (April 14, 2022)

This release adds a Value implementation for Box<T: Value> to allow recording boxed values more conveniently. In particular, this should improve the ergonomics of the implementations for dyn std::error::Error trait objects, including those added in v0.1.25.

Added

• Value implementation for Box<T> where T: Value (#2071)

Fixed

• Broken documentation links (#2068)

Thanks to new contributor @ben0x539 for contributing to this release!

0.1.25 (April 12, 2022)

This release adds additional Value implementations for std::error::Error trait objects with auto trait bounds (Send and Sync), as Rust will not auto-coerce trait objects. Additionally, it fixes a bug when setting scoped dispatchers that was introduced in the previous release (v0.1.24).

Added

• Value implementations for dyn Error + Send + 'static, dyn Error + Send + Sync + 'static, dyn Error + Sync + 'static (#2066)

Fixed

• Failure to use the global default dispatcher if a thread has set a scoped default prior to setting the global default, and unset the scoped default after setting the global default (#2065)

Thanks to @lilyball for contributing to this release!

0.1.24 (April 1, 2022)

This release fixes a bug where setting NoSubscriber as the local default would not disable the global default subscriber locally.

Fixed

• Setting NoSubscriber as the local default now correctly disables the global default subscriber (#2001)
• Fixed compilation warnings with the "std" feature disabled (#2022)

Changed

• Removed unnecessary use of write! and format_args! macros (#1988)

0.1.23 (March 8, 2022)

Changed

• Removed #[inline] attributes from some Dispatch methods whose callers are now inlined (#1974)
• Bumped minimum supported Rust version (MSRV) to Rust 1.49.0 (#1913)

0.1.22 (February 3, 2022)

This release adds experimental support for recording structured field values using the valuable crate. See this blog post for details on valuable.

Note that valuable support currently requires --cfg tracing_unstable. See the documentation for details.

Added

• field: Experimental support for recording field values using the valuable crate (#1608, #1888, #1887)
• field: Added ValueSet::record method (#1823)
• subscriber: Default impl for NoSubscriber (#1785)
• metadata: New Kind::HINT to support the enabled! macro in tracing (#1883, #1891)

Fixed

• Fixed a number of documentation issues (#1665, #1692, #1737)

Thanks to @xd009642, @Skepfyr, @guswynn, @Folyd, and @mbergkvist for contributing to this release!

0.1.21 (October 1, 2021)

This release adds support for recording Option<T> where T: Value as typed tracing field values.

Added

• field: Value impl for Option<T> where T: Value (#1585)

Fixed

• Fixed deprecation warnings when building with default-features disabled (#1603, #1606)
• Documentation fixes and improvements (#1595, #1601)

Thanks to @brianburgers, @DCjanus, and @matklad for contributing to this release!

0.1.20 (September 12, 2021)

This release adds support for f64 as one of the tracing-core primitive field values, allowing floating-point values to be recorded as typed values rather than with fmt::Debug. Additionally, it adds NoSubscriber, a Subscriber implementation that does nothing.

Added

• subscriber: NoSubscriber, a no-op Subscriber implementation (#1549)
• field: Added Visit::record_f64 and support for recording floating-point values (#1507)

Thanks to new contributors @jsgf and @maxburke for contributing to this release!
