This release of tracing-attributes fixes a bug where compiler diagnostic spans for type errors in #[instrument]ed async fns have the location of the #[instrument] attribute rather than the location of the actual error, and a bug where inner attributes in #[instrument]ed functions would cause a compiler error.
#[instrument]ed functions (#2307)async fns (#2270)syn dependency to fix compilation with -Z minimal-versions (#2246)Thanks to new contributors @compiler-errors and @e-nomem, as well as @CAD97, for contributing to this release!
This release fixes an issue where using the err or ret arguments to #[instrument] along with an overridden target, such as
#[instrument(target = "...", err, ret)]
would not propagate the overridden target to the events generated for errors/return values.
#[instrument(err)] or #[instrument(ret)] not inheriting an overridden target (#2184)Thanks to new contributor @tbraun96 for contributing to this release!
This release adds support for setting explicit parent and follows-from spans in the #[instrument] attribute.
#[instrument(follows_from = ...)] argument for setting one or more follows-from span (#2093)#[instrument(parent = ...)] argument for overriding the generated span's parent (#2091)async blocks in expanded code (causes a Clippy warning) (#2090)Thanks to @jarrodldavis, @ben0x539, and new contributor @jswrenn for contributing to this release!
--minimal-versions due to a too-permissive syn dependency (#1960)Thanks to new contributor @udoprog for contributing to this release!
This release introduces a new #[instrument(ret)] argument to emit an event with the return value of an instrumented function.
#[instrument(ret)] to record the return value of a function (#1716)err(Debug) argument to cause #[instrument(err)] to record errors with Debug rather than `Display (#1631)rust-analyzer (#1634)Thanks to @Swatinem, @hkmatsumoto, @cynecx, and @ciuncan for contributing to this release!
This release fixes issues introduced in v0.1.17.
#[instrument] on an async fn that returns an impl Trait value that includes a closure (#1616)clippy::suspicious_else_formatting warnings due to rust-lang/rust-clippy#7760 and rust-lang/rust-clippy#6249 (#1617)clippy::let_unit_value lints when using #[instrument] (#1614)This release significantly improves performance when #[instrument]-generated spans are below the maximum enabled level.
Thanks to @oli-obk for contributing to this release!
This release adds a new #[instrument(skip_all)] option to skip recording all arguments to an instrumented function as fields. Additionally, it adds support for recording arguments that are tracing primitive types as typed values, rather than as fmt::Debug.
