| </span><span class="doccomment">//! `tinyvec` provides 100% safe vec-like data structures. |
| //! |
| //! ## Provided Types |
| //! With no features enabled, this crate provides the [`ArrayVec`] type, which |
| //! is an array-backed storage. You can push values into the array and pop them |
| //! out of the array and so on. If the array is made to overflow it will panic. |
| //! |
| //! Similarly, there is also a [`SliceVec`] type available, which is a vec-like |
| //! that's backed by a slice you provide. You can add and remove elements, but |
| //! if you overflow the slice it will panic. |
| //! |
| //! With the `alloc` feature enabled, the crate also has a [`TinyVec`] type. |
| //! This is an enum type which is either an `Inline(ArrayVec)` or a `Heap(Vec)`. |
| //! If a `TinyVec` is `Inline` and would overflow it automatically transitions |
| //! itself into being `Heap` mode instead of a panic. |
| //! |
| //! All of this is done with no `unsafe` code within the crate. Technically the |
| //! `Vec` type from the standard library uses `unsafe` internally, but *this |
| //! crate* introduces no new `unsafe` code into your project. |
| //! |
| //! The limitation is that the element type of a vec from this crate must |
| //! support the [`Default`] trait. This means that this crate isn't suitable for |
| //! all situations, but a very surprising number of types do support `Default`. |
| //! |
| //! ## Other Features |
| //! * `grab_spare_slice` lets you get access to the "inactive" portions of an |
| //! ArrayVec. |
| //! * `rustc_1_40` makes the crate assume a minimum rust version of `1.40.0`, |
| //! which allows some better internal optimizations. |
| //! * `serde` provides a `Serialize` and `Deserialize` implementation for |
| //! [`TinyVec`] and [`ArrayVec`] types, provided the inner item also has an |
| //! implementation. |
| //! |
| //! ## API |
| //! The general goal of the crate is that, as much as possible, the vecs here |
| //! should be a "drop in" replacement for the standard library `Vec` type. We |
| //! strive to provide all of the `Vec` methods with the same names and |
| //! signatures. The exception is that the element type of some methods will have |
| //! a `Default` bound that's not part of the normal `Vec` type. |
| //! |
| //! The vecs here also have a few additional methods that aren't on the `Vec` |
| //! type. In this case, the names tend to be fairly long so that they are |
| //! unlikely to clash with any future methods added to `Vec`. |
| //! |
| //! ## Stability |
| //! * The `1.0` series of the crate works with Rustc `1.34.0` or later, though |
| //! you still need to have Rustc `1.36.0` to use the `alloc` feature. |
| //! * The `2.0` version of the crate is planned for some time after the |
| //! `min_const_generics` stuff becomes stable. This would greatly raise the |
| //! minimum rust version and also allow us to totally eliminate the need for |
| //! the `Array` trait. The actual usage of the crate is not expected to break |
| //! significantly in this transition. |
