# v0.3

## v0.3.0

* Added `ValueSize` trait as a generalization of `std::mem::size_of`
* Blanket-implemented `MemSize` for all `T: ValueSize + HeapSize`, implementing
`MemSize` directly is now impossible
* Added option for specialized size estimation methods for `Iterator`s and
`ExactSizeIterator`s of items with allocated memory
* Improved performance of various size estimations, especially in non-LTO
profiles

# v0.2

## v0.2.1

* Implemented `MemSize` for `Box<T>` even if `T: Sized` is not satisfied
* Improved performance of reallocation
* Bump `hashbrown` to `0.14`
* Fixed size estimation for `HashMap`, `Mutex`, and `RwLock`
* Fixed automatic reallocation increasing capacity by a factor of 4 instead of 2
* Fixed `LruCache::clear` not dropping entries and not resetting LRU and MRU

## v0.2.0

* Introduced new API for `LruCache` to better match `HashMap`
    * `try_insert`
    * `retain`
    * `get_entry`/`peek_entry` to match `HashMap`'s `get_key_value`
    * `into_keys`/`into_values`
    * `hasher`
* Introduced new `HeapSize` trait that determines the size of referenced data
    * Useful for easier `MemSize` implementation of collections
    * `MemSize` is blanket-implemented for `HeapSize + Sized`
* Introduced new error types -- one for each fallible situation
    * `InsertError` for fails in `LruCache::insert`
    * `TryInsertError` for fails in `LruCache::try_insert`
    * `MutateError` for fails in `LruCache::mutate`
    * Removed `LruError`
* Some minor documentation improvements
* Internal restructuring which may change the performance in some situations

# v0.1

## v0.1.5

* Allowed `mutate` to take an `FnOnce` instead of an `Fn`
* Implemented `Debug` for `LruCache` when `K` and `V` also implement `Debug`
* Significant restructuring with performance improvements for most methods

## v0.1.4

* Exposed an `entry_size` method to compute the requirement of entries
* Fixed `reserve` and `try_reserve` not handling errors correctly
* Improved documentation

## v0.1.3

* Implemented `Send` and `Sync` for `LruCache`
* Minor performance improvement for cloning and reallocating
* Fixed typo in documentation

## v0.1.2

* Fixed documentation errors

## v0.1.1

* Fixed documentation errors
