[dependabot]

Bumps atomic-time from 0.1.5 to 0.2.1.

Changelog

Sourced from atomic-time's changelog.

0.2.1

BUG FIXES

• decode_duration and decode_option_duration no longer panic on non-canonical input. Previously, decode_duration(u128::MAX) and decode_option_duration(u128::MAX) called Duration::new with out-of-range nanoseconds, which panicked when the carry overflowed the seconds field. The decoders now normalize the nanosecond count and saturate at Duration::MAX instead.
• decode_instant_from_duration no longer panics on extreme Duration values. Decoding a Duration far exceeding the platform's Instant range (e.g. Duration::new(u64::MAX, 999_999_999)) caused instant_now + delta to overflow and panic — including through the serde Deserialize impls for AtomicInstant and AtomicOptionInstant, where a malformed JSON payload would crash the process. The function now uses Instant::checked_add / checked_sub and saturates at instant_now on overflow.
• Thread-safety tests now use CAS (fetch_update) instead of non-atomic load+store, and assert exact final values. The previous tests could silently lose concurrent updates and still pass because their assertions were too loose.
• Integration test suite now actually runs. The six binaries under integration/src/bin/ had fn main() with assertions but no #[test] functions, so cargo test reported 0 tests. Each binary now has a #[cfg(test)] module that wraps the logic, yielding 6 real test results.

PERFORMANCE

• Added #[inline] to all hot-path wrapper methods (new, load, store, swap, compare_exchange, compare_exchange_weak, fetch_update) and the public encode_* / decode_* helpers across all six atomic types. This helps downstream non-LTO builds avoid call overhead on these tiny wrappers.

OTHER

• Benchmark "contended write" group renamed to load_under_write_contention to accurately reflect what it measures (load latency on the main thread while background threads write, not write latency). A new contended_store group was added that benchmarks real store and swap latency under write contention. README tables updated with the corrected labels and fresh numbers.

0.2.0
