This backports PR #991 to v0.1.x. This is primarily necessary for the MSRV bump, since some dependencies no longer compile on Rust 1.40.0. This has already been approved on `master`, in PR #991, so it should be fine to ship. ## Motivation This will avoid breaking CI on new releases of clippy. It also makes the code a little easier to read. ## Solution - Convert `match val { pat => true, _ => false }` to `matches!(val, pat)` - Remove unnecessary closures - Convert `self: &mut Self` to `&mut self` This bumps the MSRV to 1.42.0 for `matches!`. The latest version of rust is 1.46.0, so as per https://github.com/tokio-rs/tracing#supported-rust-versions this is not considered a breaking change. I didn't fix the following warning because the fix was not trivial/needed a decision: ``` warning: you are deriving `Ord` but have implemented `PartialOrd` explicitly --> tracing-subscriber/src/filter/env/field.rs:16:32 | 16 | #[derive(Debug, Eq, PartialEq, Ord)] | ^^^ | = note: `#[warn(clippy::derive_ord_xor_partial_ord)]` on by default note: `PartialOrd` implemented here --> tracing-subscriber/src/filter/env/field.rs:98:1 | 98 | / impl PartialOrd for Match { 99 | | fn partial_cmp(&self, other: &Self) -> Option<Ordering> { 100 | | // Ordering for `Match` directives is based first on _whether_ a value 101 | | // is matched or not.

tracing-journald
Support for logging [tracing][tracing] events natively to journald,
preserving structured information.
Overview
tracing is a framework for instrumenting Rust programs to collect
scoped, structured, and async-aware diagnostics. tracing-journald provides a
tracing-subscriber::Layer implementation for logging tracing spans
and events to systemd-journald, on Linux distributions that use
systemd.
Compiler support: requires rustc 1.42+
Supported Rust Versions
Tracing is built against the latest stable release. The minimum supported version is 1.42. The current Tracing version is not guaranteed to build on Rust versions earlier than the minimum supported version.
Tracing follows the same compiler support policies as the rest of the Tokio project. The current stable Rust compiler and the three most recent minor versions before it will always be supported. For example, if the current stable compiler version is 1.45, the minimum supported version will not be increased past 1.42, three minor versions prior. Increasing the minimum supported compiler version is not considered a semver breaking change as long as doing so complies with this policy.
