[3.2.1] - 2024-02-01

FIXED

• is_full() no longer panics with full bitmaps of size 32 or multiples thereof. (#19, #27)

[3.2.0] - 2022-04-30

ADDED

• Bitmap now implements TryFrom<&[u8]> and AsRef<[u8]>, and an as_bytes() method was added, to facilitate conversion to and from byte arrays.
• The iterator is now bidirectional, and next_index, prev_index and last_index methods, with corresponding false_index variants, have been added. (#14)

[3.1.0] - 2021-04-30

ADDED

• The methods first_false_index() and is_full() have been added to Bitmap. (#12)

FIXED

• The previous version broke the no_std feature; it has now been restored. (#11)

[3.0.0] - 2021-04-26

CHANGED

• This crate now uses const generics, rather than the typenum crate, to encode numerical values in types. This means you can now use plain integers in the Bitmap type, eg. Bitmap<32>, rather than the old Bitmap<typenum::U32>. (#8, #9)

ADDED

• Bitmap now implements Hash, Eq, PartialOrd and Ord. (#7)
• The as_value() method has been added to Bitmap, to get a reference to the underlying value. (#7)
• bitmaps::Iter now implements Clone and Debug. (#4)

[2.1.0] - 2020-03-26

ADDED

• There is now a std feature flag, on by default, which you can disable to get a no_std crate.

[2.0.0] - 2019-09-09

CHANGED

• Bits now does a lot less work, which is now being done instead by the BitOps trait on its storage type. This turns out to improve compilation time quite considerably. If you were using methods on Bits directly, they will have moved to BitOps.
• Debug now prints a single hex value for the entire bitmap, rather than deferring to the storage type.
• Iter now takes a reference instead of a copy, which is more sensible for larger bitmaps.

ADDED

• Bitmap now implements BitAnd, BitOr, BitXor, their equivalent assignation traits, and Not, meaning you can now use bitwise operators on them, even the very big array-of-u128 ones.
• A Bitmap::mask() constructor has been added, to construct bitmasks more efficiently, now that there are bitwise operators to use them with.

[1.0.0] - 2019-09-06

Initial release.
