the following Cargo features: - `nightly`: Enables nightly-only features including: `#[may_dangle]`. - `serde`: Enables serde serialization support. +- `rkyv`: Enables rkyv serialization support. - `rayon`: Enables rayon parallel iterator support. - `raw`: Enables access to the experimental and unsafe `RawTable` API. - `inline-more`: Adds inline hints to most functions, improving run-time performance at the cost of compilation time. (enabled by default) -- `bumpalo`: Provides a `BumpWrapper` type which allows `bumpalo` to be used for memory allocation. - `ahash`: Compiles with ahash as default hasher. (enabled by default) -- `ahash-compile-time-rng`: Activates the `compile-time-rng` feature of ahash. For targets with no random number generator -this pre-generates seeds at compile time and embeds them as constants. See [aHash's documentation](https://github.com/tkaitchuck/aHash#flags) (disabled by default) +- `allocator-api2`: Enables support for allocators that support `allocator-api2`.
