Changelog

master

  • Extract tock-registers to dedicated reposity.

v0.9

There is a small breaking change, described below, which addresses semantic confusion around matches_any(). The interface has changed, so this should result in compile-time awareness rather than any silent behavioral changes.

Breaking Changes

tock/tock#3336 480ee65139f1e51c149236a1b3e47cd61832ac80 Rename matches_any() to any_matching_bits_set(), implement matches_any()

The current implementation of matches_any() does not implement the functionality the name implies. This commit renames the existing implementation to a name which better describes its functionality, and introduces a new matches_any() function (with a different interface) that actually correctly implements the functionality suggested by the name. This commit also adds several tests to the tock-registers test suite to verify the new version works as expected, and removes a feature gate on a feature that no longer exists for the crate which was preventing some of the tock-registers teste suite from being run as part of cargo test.

Other changes:

  • #3687: derive Debug on Value
  • #3582: Update rust-toolchain to nightly of 2023-07-30

v0.8.1

A point release to allow multiple invocations of register_fields! in the same module. See the PR and linked Issue for details.

  • #3230: don't encapsulate test_fields! tests in mod

v0.8

tock-registers now supports stable Rust!

There is a small breaking change, documented below, required to support Rust 2021 edition. Most of the remaining changes are improvements to the internal self-testing infrastructure and documentation. There are also some additions to FieldValue to improve ergonomics.
