Version 1.0.2 ============= - Fixed the `new_key_type!` macro, it assumed the `Key` trait was in scope. - Updated code base with more stringent (clippy) warnings, and many small code quality and documentation changes. - Documented the minimum required stable Rust version, which is 1.49. Version 1.0.1 ============= - Fixed an instance where an uninitialized [u32; N] was created. The uninitialized values were never read - the code always initialized them before reading - but simply having the variable be uninitialized (despite all bit patterns being valid) is technically undefined behavior. Version 1.0.0 ============= - Removed all `Copy` trait restrictions of value types stable Rust! There are no longer any restrictions on the types you can store in any of the slot maps. For that reason `Slottable` was deprecated as well. - `no_std` support was added, use it by opting out of the default feature `std`. - Added `sm.get_disjoint_mut([k1, k2, ...])` which allows you to get mutable references from multiple disjoint keys at the same time. This requires `min-const-generics` to be stabilized, so until Rust 1.51 comes out this is only available on nightly by setting the `unstable` feature. - Added an `Entry` API to the secondary maps. - Added `derive(Clone)` for iterators where possible. - Replaced `Into` with `Key::data()`. - `SecondaryMap` now uses minimal space overhead. Each slot now uses `max(sizeof(T), 4)` bytes. - Moved `SlotMap` to the `basic` module. Version 0.4.0 ============= - Codebase moved to 2018 Edition. - Reintroduce `DenseSlotMap` - an overzealous removal in 0.3.0. - Added support for `try_reserve`. - Added support for custom hashers in `SparseSecondaryMap`. - `SparseSecondaryMap` and `SecondaryMap` can now be cloned. - Keys have a more terse debug output. - Fixed a bug that caused an overflowing left shift on 32-bit targets. Version 0.3.0 ============= - Massive rework, with a focus on secondary maps and custom keys to prevent cross-slotmap key usage. - Removed `DenseSlotMap` in favour of `HopSlotMap` as the latter performs better when secondary maps are in use. - Unfortunately due to the redesign the first slot in a slot map must now always be empty. This means some deserializations of slot maps serialized with a version before 0.3.0 can fail. - Added `SecondaryMap` and `SparseSecondaryMap`, which allows you to associate extra data with keys given by a slot map. - Added `DefaultKey`, custom key types, and support for them on all slot maps and secondary maps. You must now always specify the key type you're using with a slot map, so `SlotMap` would be `SlotMap`. It is recommended to make a custom key type with `new_key_type!` for any slot map you create, as this entirely prevents using the wrong key on the wrong slot map. - `KeyData` now has `as_ffi` and `from_ffi` functions that convert the data that makes up a key to/from an `u64`. This allows you to use slot map keys as opaque handles in FFI code. Version 0.2.1 ============= - Fixed a potential uninitialized memory vulnerability. No uninitialized memory was read or used directly, but Rust's assumptions could lead to it. Yanked all previous versions as they were all vulnerable. - Made a `Key` member non-zero so that `Option` is optimized. Version 0.2.0 ============= Start of version history.
