This branch is @dzvon's PR #1508, with the following changes:

  • Add a newtype wrapping the error counter to hide that it's internally
    an Arc<AtomicUsize>. This would allow us to make additional changes
    to the implementation without potentially causing breaking changes.

  • Use saturating arithmetic when incrementing the counter to avoid
    wrapping to 0 on overflows. This is more likely to be an issue on
    32-bit platforms.

This is a breaking change that will be released as part of
tracing-appender 0.2.

Closes #1508

Description from @dzvon's original PR:

Motivation

Currently, tracing-appender crate cannot be compiled on PowerPC
platform. Because

PowerPC and MIPS platforms with 32-bit pointers do not have
AtomicU64 or AtomicI64 types.

quote from std library docs.
(https://doc.rust-lang.org/std/sync/atomic/index.html#portability)

Solution

Change AtomicU64 to AtomicUsize.

appender: prepare to release v0.2.0
a4a121c 
# 0.2.0 (October 22, 2021)

This breaking change release adds support for the new v0.3.x series of
`tracing-subscriber`. In addition, it resolves the security advisory for
the `chrono` crate, [RUSTSEC-2020-0159].

This release increases the minimum supported Rust version (MSRV) to
1.51.0.
### Breaking Changes

- Updated `tracing-subscriber` to v0.3.x ([#1677])
- Changed `NonBlocking::error_counter` to return an `ErrorCounter` type,
  rather than an `Arc<AtomicU64>` ([#1675])
  ### Changed

- Updated `tracing-subscriber` to v0.3.x ([#1677])
  ### Fixed

- **non-blocking**: Fixed compilation on 32-bit targets ([#1675])
- **rolling**: Replaced `chrono` dependency with `time` to resolve
  [RUSTSEC-2020-0159] ([#1652])
- **rolling**: Fixed an issue where `RollingFileAppender` would fail to
  print errors that occurred while flushing a previous logfile ([#1604])

Thanks to new contributors @dzvon and @zvkemp for contributing to this
release!
