### 0.8.1 (2022-10-20)


### Bug Fixes

* **toad-msg:** update toad-common 0.10 -> 0.11 ([#145](https://github.com/clov-coffee/toad/issues/145)) ([62a05ce](https://github.com/clov-coffee/toad/commit/62a05ce433d253d2a98722807cd031b9fba8176d))

## 0.8.0 (2022-10-20)


### ⚠ BREAKING CHANGES
 * removed `TryConsumeNBytes`
 * removed a type parameter from `Message`
    * from `Message<PayloadBytes, OptionBytes, Options>`
    * to `Message<PayloadBytes, Options>`
 * added trait bounds for `Message<PayloadBytes, Options>` impls (non-breaking if you're using `Vec` or `tinyvec::ArrayVec`)
    * `PayloadBytes: AppendCopy<u8>`
    * `Options: AppendCopy<u8>`
 * added trait bound `A: AsRef<[u8]>` for `TryFromBytes<A>`
 * changed `TryFromBytes::<A>::try_from_bytes`
    * from `fn<I: Iterator<...>>(bs: I) -> Result<...>`
    * to `fn(bs: A) -> Result<...>`
 * changed trait bound on `A` in `TryConsumeBytes<A>`
    * from `A: Iterator<...>`
    * to `A: AsRef<[u8]>`
 * changed `TryConsumeBytes::<A>::try_consume_bytes`
    * from `fn try_consume_bytes(bytes: &mut I) -> Result<Self, Self::Error>`
    * to `fn try_consume_bytes(bytes: &mut Cursor<A>) -> Result<Self, Self::Error>;`
 * refactored module structure (most likely non-breaking since they were all `pub` but `#[doc(hidden)]`)

### Features
none

### Bug Fixes
 * removed trait bounds on all struct type parameters, but kept the trait bounds on the impls
    * _the data structure doesn't care what it stores, but the **behavior** definitely does_

### Performance Improvements
 * rewrote message parsing to use the new cursor type in toad-common
    * navigating buffers is now constant time from linear time
    * filling toad-msg data structures by `Extend`ing from the source byte buffer should be many many times faster now
       * this is owed to `Vec` and `tinyvec::ArrayVec` using more specialized "copy to end from slice" implementations that use `ptr::non_overlapping_copy` (See `toad_common::AppendCopy`) instead of copying one at a time
