vob 3.0.6 (2025-08-14)

  • Transparently optimise iter_{set|unset}_bits(...).count() to use platform "count bits" directly, rather than forcing the full iterator to execute. Depending on your machine, this can lead to savings of 2-3 orders of magnitude.

  • Implement DoubleEndedIterator and FusedIterator for Iter{Set|Unset}Bits.

vob 3.0.5 (2025-06-25)

  • Add unchecked_get and unchecked_set.

vob 3.0.4 (2025-03-17)

  • Drop support for Rust pre-1.37.

  • Add an optional bincode dependency, which can be used as an alternative to serde for encoding / decoding.

  • Use Criterion for internal benchmarking and add several benchmarks.

vob 3.0.3 (2022-08-02)

  • Update dependencies.

vob 3.0.2 (2022-07-25)

  • Add from_elem_with_storage_type as a dual of new_with_storage_type.

vob 3.0.1 (2021-10-22)

  • Implement std::ops::{BitOrAssign, BitOr, BitAndAssign, BitAnd, BitXorAssign, BitXor}. Note that, as with Vob's other bit-wise operations, these will panic if the two Vobs in question are not of equal length.

vob 3.0.0 (2021-09-20)

Breaking changes

  • Vob::from_elem(value: bool, len: usize) now takes the value first and the number of repetitions of that value second to mirror the most common way this function is defined elsewhere.

  • The vob! macro's repetition form now mirrors vec!, so vob![val; len] is equivalent to Vec::from_elem(val, len).

vob 2.0.6 (2021-01-25)

  • Add get_storage to the unsafe_internals portion of the API.
  • Clearly document the invariants users must maintain when using the unsafe parts of the API.

vob 2.0.5 (2020-09-02)

  • Use rustfmt stable.
  • Remove unnecessary fn main wrappers in doctest examples.
  • Clean up two remaining #[macro use] extern crate vob; lines from examples.

vob 2.0.4 (2019-11-21)

  • License as dual Apache-2.0/MIT (instead of a more complex, and little understood, triple license of Apache-2.0/MIT/UPL-1.0).

vob 2.0.3 (2019-08-21)

  • Port to Rust 2018.
  • Remove local copy of Bounds since it is now part of stable Rust.
  • On rustc-1.37 and later, automatically use reverse_bits (this automatically includes the current nightly version of rustc).

vob 2.0.2 (2018-12-18)

  • Further speed up iter_\[set|unset\]_bits for cases where set/unset bits are fairly randomly distributed (by approximately 10%).

vob 2.0.1 (2018-12-11)

  • Substantially speed up iter_\[set|unset\]_bits for the common case where all bits are set/unset (respectively). This leads to a 3x improvement in such cases, with no measurable slowdown in the general case.

vob 2.0.0 (2018-10-10)

  • Change set so that if passed an out of bounds index it panics (previously it returned None, but since one doesn't generally check the return value of set, this led to errors being overlooked).

vob 1.3.2 (2018-06-30)

  • Improve performance of the xor, and, and or functions.
  • Add fast_reverse feature: on nightly, we automatically try to use the fast_reverse function to improve performance.

vob 1.3.1 (2018-06-20)

  • Don't overallocate memory in new_with_storage_type.

vob 1.3.0 (2018-06-11)

  • Add extend_from_vob function.
  • Add unsafe_internals feature, which allows external crates unsafe access to Vob's internal (useful for speed, but bad for forwards compatibility!).
  • Various performance improvements.
  • Use rustfmt.

vob 1.2.0 (2018-05-08)

  • Add from_bytes function.

vob 1.1.0 (2018-03-29)

  • Add serde feature to enable Serde support.

vob 1.0.0 (2018-03-14)

First stable release.
