| 1 | //! **arrayvec** provides the types [`ArrayVec`] and [`ArrayString`]: |
|---|---|
| 2 | //! array-backed vector and string types, which store their contents inline. |
| 3 | //! |
| 4 | //! The arrayvec package has the following cargo features: |
| 5 | //! |
| 6 | //! - `std` |
| 7 | //! - Optional, enabled by default |
| 8 | //! - Use libstd; disable to use `no_std` instead. |
| 9 | //! |
| 10 | //! - `serde` |
| 11 | //! - Optional |
| 12 | //! - Enable serialization for ArrayVec and ArrayString using serde 1.x |
| 13 | //! |
| 14 | //! - `zeroize` |
| 15 | //! - Optional |
| 16 | //! - Implement `Zeroize` for ArrayVec and ArrayString |
| 17 | //! |
| 18 | //! ## Rust Version |
| 19 | //! |
| 20 | //! This version of arrayvec requires Rust 1.51 or later. |
