   1 Recent Changes (arrayvec)
   2 =========================
   3
   4 ## 0.7.1
   5
   6 - Add new ArrayVec methods `.take()` and `.into_inner_unchecked()` by @conradludgate
   7 - `clone_from` now uses `truncate` when needed by @a1phyr
   8
   9 ## 0.7.0
  10
  11 - `fn new_const` is now the way to const-construct arrayvec and arraystring,
  12   and `fn new` has been reverted to a regular "non-const" function.
  13   This works around performance issue #182, where the const fn version did not
  14   optimize well. Change by @bluss with thanks to @rodrimati1992 and @niklasf
  15   for analyzing the problem.
  16
  17 - The deprecated feature flag `unstable-const-fn` was removed, since it's not needed
  18
  19 - Optimize `.retain()` by using the same algorithm as in std, change by @niklasf,
  20   issue #174. Original optimization in Rust std by @oxalica in rust-lang/rust/pull/81126
  21
  22 ## 0.6.1
  23
  24 - The ``ArrayVec::new`` and ``ArrayString::new`` constructors are properly
  25   const fns on stable and the feature flag ``unstable-const-fn`` is now deprecated.
  26   by @rodrimati1992
  27
  28 - Small fix to the capacity check macro by @Xaeroxe
  29 - Typo fix in documentation by @cuviper
  30 - Small code cleanup by @bluss
  31
  32 ## 0.6.0
  33
  34 - The **const generics** release 🎉. Arrayvec finally implements what it
  35   wanted to implement, since its first version: a vector backed by an array,
  36   with generic parameters for the arbitrary element type *and* backing array
  37   capacity.
  38
  39   The New type syntax is `ArrayVec<T, CAP>` where `CAP` is the arrayvec capacity.
  40   For arraystring the syntax is `ArrayString<CAP>`.
  41
  42   Length is stored internally as u32; this limits the maximum capacity. The size
  43   of the `ArrayVec` or `ArrayString` structs for the same capacity may grow
  44   slightly compared with the previous version (depending on padding requirements
  45   for the element type). Change by @bluss.
  46
  47 - Arrayvec's `.extend()` and `FromIterator`/`.collect()` to arrayvec now
  48   **panic** if the capacity of the arrayvec is exceeded. Change by @bluss.
  49
  50 - Arraystring now implements `TryFrom<&str>` and `TryFrom<fmt::Arguments>` by
  51   @c410-f3r
  52
  53 - Minimum supported rust version is Rust 1.51
  54
  55 ## 0.5.2
  56
  57 - Add `is_empty` methods for ArrayVec and ArrayString by @nicbn
  58 - Implement `TryFrom<Slice>` for ArrayVec by @paulkernfeld
  59 - Add `unstable-const-fn` to make `new` methods const by @m-ou-se
  60 - Run miri in CI and a few related fixes by @RalfJung
  61 - Fix outdated comment by @Phlosioneer
  62 - Move changelog to a separate file by @Luro02
  63 - Remove deprecated `Error::description` by @AnderEnder
  64 - Use pointer method `add` by @hbina
  65
  66 ## 0.5.1
  67
  68 - Add `as_ptr`, `as_mut_ptr` accessors directly on the `ArrayVec` by @tbu-
  69   (matches the same addition to `Vec` which happened in Rust 1.37).
  70 - Add method `ArrayString::len` (now available directly, not just through deref to str).
  71 - Use raw pointers instead of `&mut [u8]` for encoding chars into `ArrayString`
  72   (uninit best practice fix).
  73 - Use raw pointers instead of `get_unchecked_mut` where the target may be
  74   uninitialized everywhere relevant in the ArrayVec implementation
  75   (uninit best practice fix).
  76 - Changed inline hints on many methods, mainly removing inline hints
  77 - `ArrayVec::dispose` is now deprecated (it has no purpose anymore)
  78
  79 ## 0.4.12
  80
  81 - Use raw pointers instead of `get_unchecked_mut` where the target may be
  82   uninitialized everywhere relevant in the ArrayVec implementation.
  83
  84 ## 0.5.0
  85
  86 - Use `MaybeUninit` (now unconditionally) in the implementation of
  87   `ArrayVec`
  88 - Use `MaybeUninit` (now unconditionally) in the implementation of
  89   `ArrayString`
  90 - The crate feature for serde serialization is now named `serde`.
  91 - Updated the `Array` trait interface, and it is now easier to use for
  92   users outside the crate.
  93 - Add `FromStr` impl for `ArrayString` by @despawnerer
  94 - Add method `try_extend_from_slice` to `ArrayVec`, which is always
  95   effecient by @Thomasdezeeuw.
  96 - Add method `remaining_capacity` by @Thomasdezeeuw
  97 - Improve performance of the `extend` method.
  98 - The index type of zero capacity vectors is now itself zero size, by
  99   @clarfon
 100 - Use `drop_in_place` for truncate and clear methods. This affects drop order
 101   and resume from panic during drop.
 102 - Use Rust 2018 edition for the implementation
 103 - Require Rust 1.36 or later, for the unconditional `MaybeUninit`
 104   improvements.
 105
 106 ## Older releases
 107
 108 - 0.4.11
 109
 110   - In Rust 1.36 or later, use newly stable `MaybeUninit`. This extends the
 111     soundness work introduced in 0.4.9, we are finally able to use this in
 112     stable. We use feature detection (build script) to enable this at build
 113     time.
 114
 115 - 0.4.10
 116
 117   - Use `repr(C)` in the `union` version that was introduced in 0.4.9, to
 118     allay some soundness concerns.
 119
 120 - 0.4.9
 121
 122   - Use `union` in the implementation on when this is detected to be supported
 123     (nightly only for now). This is a better solution for treating uninitialized
 124     regions correctly, and we'll use it in stable Rust as soon as we are able.
 125     When this is enabled, the `ArrayVec` has no space overhead in its memory
 126     layout, although the size of the vec should not be relied upon. (See [#114](https://github.com/bluss/arrayvec/pull/114))
 127   - `ArrayString` updated to not use uninitialized memory, it instead zeros its
 128     backing array. This will be refined in the next version, since we
 129     need to make changes to the user visible API.
 130   - The `use_union` feature now does nothing (like its documentation foretold).
 131
 132
 133 - 0.4.8
 134
 135   - Implement Clone and Debug for `IntoIter` by @clarcharr
 136   - Add more array sizes under crate features. These cover all in the range
 137     up to 128 and 129 to 255 respectively (we have a few of those by default):
 138
 139     - `array-size-33-128`
 140     - `array-size-129-255`
 141
 142 - 0.4.7
 143
 144   - Fix future compat warning about raw pointer casts
 145   - Use `drop_in_place` when dropping the arrayvec by-value iterator
 146   - Decrease mininum Rust version (see docs) by @jeehoonkang
 147
 148 - 0.3.25
 149
 150   - Fix future compat warning about raw pointer casts
 151
 152 - 0.4.6
 153
 154   - Fix compilation on 16-bit targets. This means, the 65536 array size is not
 155     included on these targets.
 156
 157 - 0.3.24
 158
 159   - Fix compilation on 16-bit targets. This means, the 65536 array size is not
 160     included on these targets.
 161   - Fix license files so that they are both included (was fixed in 0.4 before)
 162
 163 - 0.4.5
 164
 165   - Add methods to `ArrayString` by @DenialAdams:
 166
 167     - `.pop() -> Option<char>`
 168     - `.truncate(new_len)`
 169     - `.remove(index) -> char`
 170
 171   - Remove dependency on crate odds
 172   - Document debug assertions in unsafe methods better
 173
 174 - 0.4.4
 175
 176   - Add method `ArrayVec::truncate()` by @niklasf
 177
 178 - 0.4.3
 179
 180   - Improve performance for `ArrayVec::extend` with a lower level
 181     implementation (#74)
 182   - Small cleanup in dependencies (use no std for crates where we don't need more)
 183
 184 - 0.4.2
 185
 186   - Add constructor method `new` to `CapacityError`.
 187
 188 - 0.4.1
 189
 190   - Add `Default` impl to `ArrayString` by @tbu-
 191
 192 - 0.4.0
 193
 194   - Reformed signatures and error handling by @bluss and @tbu-:
 195
 196     - `ArrayVec`'s `push, insert, remove, swap_remove` now match `Vec`'s
 197       corresponding signature and panic on capacity errors where applicable.
 198     - Add fallible methods `try_push, insert` and checked methods
 199       `pop_at, swap_pop`.
 200     - Similar changes to `ArrayString`'s push methods.
 201
 202   - Use a local version of the `RangeArgument` trait

 228 - 0.3.19
 229
 230   - Add new crate feature `use_generic_array` which allows using their

 232     of an `ArrayVec`.
 233
 234 - 0.3.18
 235
 236   - Fix bounds check in `ArrayVec::insert`!
 237     It would be buggy if `self.len() < index < self.capacity()`. Take note of

 252
 253   - Add feature std, which you can opt out of to use `no_std` (requires Rust 1.6
