…nsi_term (#2029) ## Motivation EnvFilter with ansi_term will say something like the following when statically disabled filters are present: ``` warning: some trace filter directives would enable traces ... = note: the static max level is `LEVEL` = help: to enable LEVEL logging, ... ``` Without the ansi_term feature, it instead says something like the following: ``` warning: some trace filter directives would enable traces ... note: the static max level is `LEVEL` note: to enable LEVEL logging, ... ``` This is due to a simple error in cfg'd code that ignores the requested prefix and always uses `note:` when `not(feature = "ansi_term")`. ## Solution Use the unused `prefix` variable to do what it does when `feature = "ansi_term"`. The output without ansi_term is now ``` warning: some trace filter directives would enable traces ... note: the static max level is `LEVEL` help: to enable LEVEL logging, ... ```

# 0.3.10 (Apr 1, 2022) This release adds several new features, including a `Filter` implementation and new builder API for `EnvFilter`, support for using a `Vec<L> where L: Layer` as a `Layer`, and a number of smaller API improvements to make working with dynamic and reloadable layers easier. ### Added - **registry**: Implement `Filter` for `EnvFilter`, allowing it to be used with per-layer filtering ([#1983]) - **registry**: `Filter::on_new_span`, `Filter::on_enter`, `Filter::on_exit`, `Filter::on_close` and `Filter::on_record` callbacks to allow `Filter`s to track span states internally ([#1973], [#2017], [#2031]) - **registry**: `Filtered::filter` and `Filtered::filter_mut` accessors ([#1959]) - **registry**: `Filtered::inner` and `Filtered::inner_mut` accessors to borrow the wrapped `Layer` ([#2034]) - **layer**: Implement `Layer` for `Vec<L: Layer>`, to allow composing together a dynamically sized list of `Layer`s ([#2027]) - **layer**: `Layer::boxed` method to make type-erasing `Layer`s easier ([#2026]) - **fmt**: `fmt::Layer::writer` and `fmt::Layer::writer_mut` accessors ([#2034]) - **fmt**: `fmt::Layer::set_ansi` method to allow changing the ANSI formatting configuration at runtime ([#2034]) - **env-filter**: `EnvFilter::builder` to configure a new `EnvFilter` prior to parsing it ([#2035]) - Several documentation fixes and improvements ([#1972], [#1971], [#2023], [#2023]) ### Fixed - **fmt**: `fmt::Layer`'s auto traits no longer depend on the `Subscriber` type parameter's auto traits ([2025]) - **env-filter**: Fixed missing help text when the `ansi` feature is disabled ([#2029]) Thanks to new contributors @TimoFreiberg and @wagenet, as well as @CAD97 for contributing to this release!

Motivation
EnvFilter with ansi_term will say something like the following when statically disabled filters are present:
Without the ansi_term feature, it instead says something like the following:
This is due to a simple error in cfg'd code that ignores the requested prefix and always uses
note:whennot(feature = "ansi_term").Solution
Use the unused
prefixvariable to do what it does whenfeature = "ansi_term".The output without ansi_term is now
