v1.6.0 (unreleased)

  • Features:
    • Add quickcheck support, gated behind the quickcheck feature.
    • Improve performance of RangeMap::gaps by efficiently seeking to the start of the query range.

v1.5.1 (2024-02-27)

  • Fixes:
    • Relax bounds on Default implementation for all map and set types. Requiring K: Default and V: Default was accidentally introduced in v1.5.0.

v1.5.0 (2024-02-09) "xfbs rampage edition"

Huge thanks to xfbs, who did pretty much all the work you see in the changelog below! 💖

  • Features:

    • Add union and intersection methods to iterate over the union or intersection of two sets.
    • Add first_range_value and last_range_value methods to map types and first and last methods to set types.
    • Add literal macros for all collection types — e.g. range_set![0..100, 200..300, 400..500].
    • Implement Default and Hash for all collection types.
    • Implement DoubleEndedIterator for all iterators.
    • Implement From<[_; N]> (e.g. From<[Range<T>; N]> for RangeSet<T>) for all collections. (Previously you could build a collection from an iterator, but not directly from an array.)
    • Implement BitOr and BitAnd for set types. (Convenience wrapper around the union and intersection methods mentioned above.)
    • Accept any R: Borrow<Range<K>> as argument to overlapping methods, allowing it to take ranges by value.

  • Changes:

    • Bump minimum supported Rust version to 1.66.0 (released 2022-12-15). This is to gain access to BTreeMap::first_key_value and BTreeMap::last_key_value, and for compatibility with new versions of some of rangemap's test dependencies.

  • Internal:

    • New benchmarks and improved test coverage.

v1.4.0 (2023-09-19)

  • Changes:
    • Bump minimum supported Rust version to 1.61.0 (released 2022-05-19). This is for compatibility with new versions of some of rangemap's test dependencies.

v1.3.1 (2023-09-19)

  • Fixes:
    • Fix PartialEq, PartialOrd, and Ord implementations for RangeMap (and RangeSet). These previously only compared the starts of ranges instead of the entire range. Thanks to https://github.com/hecrj for finding and fixing this!
  • Changes:
    • Minimum supported Rust version for running this crate's tests has increased to 1.61.0 due to a corresponding MSRV bump in a test dependency. This is causing CI builds to fail against rustc 1.56.1, but should not affect consumers of the crate. The next minor release (1.4.0) will bump the minimum supported Rust version of rangemap itself.

v1.3.0 (2023-01-03)

  • Features:
    • Add overlapping method to all collection types, which returns an iterator over all stored entries that completely or partially overlap a given range.
    • Add overlaps convenience method to all collection types, which returns whether any stored range completely or partially overlaps a given range.
    • Credit to Rua for the original implementation of these new methods. (Unfortunately I couldn't use their code directly because I made other incompatible changes.) Thanks also to rumpuslabs for their engagement.

v1.2.0 (2022-12-27)

  • Features:
    • Add clear, len, and is_empty methods for all map and set types.
  • Fixes:
    • Make const_fn feature work again. (Previous release accidentally broke the const versions of RangeMap::new and RangeSet::new.)

v1.1.0 (2022-11-12)

  • Features:
    • Implement PartialEq, Eq, PartialOrd, and Ord for all map and set types.
    • Make new functions for all map and set types const when const_fn feature is enabled.
  • Changes:
    • Bump minimum supported Rust version to 1.56.1. (Released a year ago.) This is for compatibility with new versions of some of rangemap's development dependencies.

v1.0.3 (2022-06-11)

  • Fixes:
    • Fix Gaps iterator for RangeMap yielding an empty gap for an empty outer range. Simplified gaps logic and expanded fuzz testing to better cover this and similar cases.

v1.0.2 (2022-05-17)

  • Fixes:
    • Fix empty gaps returned by Gaps iterator for RangeInclusiveMap. Added fuzz tests for Gaps iterators.

v1.0.1 (2022-01-29)

  • Fixes:
    • Fix empty gaps returned by Gaps iterator for RangeMap, and incorrect gaps returned by Gaps iterator for RangeInclusiveMap.

v1.0.0 (2022-01-28)

It's time. (No functional change.)

v0.1.14 (2021-11-16)

  • Features:
    • Expose nameable types for iterators: Iterator, IntoIterator, Gaps (for each collection type).
  • Changes:
    • Document overflow behaviour required by implementors of StepLite and StepFns.

v0.1.13 (2021-08-25)

  • Features:
    • Add serde support.

v0.1.12 (2021-08-23)

  • Features:
    • Implement more traits for all map and set types: IntoIter, FromIter, and Extend.
  • Changes:
    • Bump minimum supported Rust version to 1.46.

v0.1.11 (2021-06-30) "EOFY edition"

  • Features:
    • Support no_std environments.
  • Changes:
    • Update all dev-dependencies to latest versions.

v0.1.10 (2021-02-23)

  • Fixes:
    • Fix performance regression introduced in v0.1.9, which made inserts extremely slow for large maps.

v0.1.9 (2021-02-23)

  • Fixes:
    • Fix coalescing of contiguous ranges. In some cases RangeMap and RangeInclusiveMap would leave two separate contiguous ranges with the same value instead of combining them into one.

v0.1.8 (2020-11-22)

  • Features:
    • Implement Debug for all map and set types.

v0.1.7 (2020-09-07)

  • Features:
    • Add gaps method to all map and set types for iterating over sub-ranges of a given outer range that are not covered by any stored range.

v0.1.6 (2020-07-15)

  • Features:
    • Add RangeInclusiveMap and RangeInclusiveSet types for storing closed ranges.
