## Unreleased

## [0.7.1] - 2024-10-30
### Added
- #![no_std]

## [0.7.0] - 2024-03-27
### Changed
- Unimock bumped to 0.6.
- Reworked async support. Rust now has native support for async functions in traits, which means that entrait doesn't need to interact with this in a hacky way anymore.
- Minimum Supported Rust Version bumped to 1.75.
- `async` entrait functions will get rewritten to the `fn f(..) -> impl Future<Output = ?>` form when appearing in trait definitions, due to the [async_fn_in_trait](https://doc.rust-lang.org/beta/rustc/lints/listing/warn-by-default.html#async-fn-in-trait) warn-by-default lint.
### Added
- Improved interoperability with the `async_trait` macro, for scenarios where dynamic dispatch-delegation is used in combination with `async`.
- `?Send` argument to the entrait macro, for allowing opt-out of `Send` bounds for the `Future`s generated from `async` trait methods.
### Removed
- features `boxed-futures`, `use-boxed-futures` and `use-associated-futures`.

## [0.6.0] - 2023-10-15
### Changed
- Unimock bumped to 0.5.
### Fixed
- Stop adding lifetimes to trait generic params ([#30](https://github.com/audunhalland/entrait/pull/30))

## [0.5.3] - 2023-03-24
### Changed
- `syn` upgraded to version 2.

## [0.5.2] - 2022-12-30
### Added
- `delegate_by=ref` in favor of `delegate_by = Borrow` (deprecation of the latter). This encourages using `AsRef` instead of `Borrow`.
- `#[entrait(ref)]` on deep delegation impl blocks.

## [0.5.1] - 2022-12-30
### Fixed
- Make examples compile out of the box, by selecting the correct features.
- Entrait methods now correctly mirror attributes like `#[cfg]`.

## [0.5.0] - 2022-12-10
### Changed
- Feature `async-trait` renamed to `boxed-futures`.
- Feature `use-async-trait` renamed to `use-boxed-futures`.
- Feature `use-associated-future` renamed to `use-associated-futures`.
- `unimock` optional dependency upgraded to `0.4`.
- New entrait option `mock_api` to optionally generate a mock setup interface.
### Removed
- `entrait_impl`. Replaced by `#[entrait] impl TraitImpl for MyType {}`.
- `entrait_dyn_impl`. Replaced by `#[entrait(dyn)] impl TraitImpl for MyType {}`.

## [0.4.6] - 2022-08-17
### Added
- Support for `#[entrait] impl TraitImpl for Type {}` for inverted dependencies. Modules will be deprecated in next release, since this is much cleaner.
### Changed
- Deprecated the recently added `#[entriat_impl]` and `#[entrait_dyn_impl]` in favor of the impl block syntax, because that idea didn't yet exist at the time of original implementation.

## [0.4.5] - 2022-08-11
### Changed
- Docs: move "Module support" to later in the Introduction section, because it interrupts the original flow of the documentation.

## [0.4.4] - 2022-08-11
### Added
- Dependency inversion support with the `#[entrait(TraitImpl, delegate_by = DelegationTrait)] trait Trait {}` syntax.
- #[inline] attribute on small, delegating methods.
### Changed
- Make zero-cost futures using a separate macro (`entrait::static_async::async_trait`), comparable to `async_trait`.

## [0.4.3] - 2022-08-01
### Added
- Support for using the entrait attribute on a module.

## [0.4.2] - 2022-07-31
### Added
- `delegate_by = Borrow` option for traits (supports dyn trait leaf dependencies).
### Fixed
- Fix hygiene problem when a parameter has the same ident as the function. Fix uses a hack that appends an underscore to the trait fn param.
- Improved generic params and where clause generation, should generate some fewer tokens overall.
- Doc: Bring back `Impl<T>` impl block code generation example.

## [0.4.1] - 2022-07-25
### Fixed
- Extract idents from destructured fn params and use those in trait fn signature, given that the ident is unambigous.
### Changed
- Refactor/optimize internal where clause generator, avoiding syn::parse_quote

## [0.4.0] - 2022-07-24
### Added
- `implementation` as a dependency, to help users getting started.
- `unimock` feature. Enabling the features downstream will generate mocks upstream.
- `entrait_export` macro and `export` option, for exporting optional mocks from libraries.
- `async-trait` feature for adding a re-export of the async-trait crate.
- `use-async-trait` and `use-associated-future` features for global selection of async strategy.
- Support for generic functions.
- Support for entraiting a trait.
### Changed
- Restructure lib docs.
### Removed
- Support for parameter-less functions without use of `no_deps`. This is technically 'breaking' but can also be seen as a bugfix.
- Submodule import paths (`entrait::unimock`, etc). This is instead enabled by using features.
### Fixed
- Destructured fn params in the original function. Entrait will generate a param name to use in the trait.

## [0.3.4] - 2022-06-30
### Added
- More cargo keywords, categories.

## [0.3.3] - 2022-06-29
### Changed
- The implementation of leaf/concrete dependencies now works a bit differently.
  Instead of the trait being implemented for some concrete `T` in `Impl<T>`, `T` is made generic, but with a `T: Trait` bound.
  Because of that, the trait gets implemented a second time: Directly for the concrete `T`.
  This makes it much easier to seamlessly integrate modular apps divided into many crates.
### Fixed
- Every kind of deps parameter that is not recognized as generic is now legal, and interpreted as being concrete.

## [0.3.2] - 2022-06-27
### Added
- `associated_future` experimental nightly feature, for zero cost futures.

## [0.3.1] - 2022-06-22
### Added
- `no_deps` support. Add this attribute to not interpret the first parameter as a deps parameter.
- default values for config attributes (may skip '= value')

## [0.3.0] - 2022-06-03
### Changed
- Bump unimock to 0.2.0, which removes the need for generic assocated types support

## [0.3.0-beta.0] - 2022-05-15
### Changed
- Improve outputted spans to reflect macro arguments instead of input function
- Bump unimock to next major version (0.2.0)
- Support explicit trait visibility, private/inherited by default

### Removed
- Support for `for T` syntax. The implementations are instead automatically registered with the `implementation` crate.

## [0.2.1] - 2022-03-13
### Added
- `mockall=test` + `unimock=test` support

## [0.2.0] - 2022-03-13
### Added
- `unimock` support.
- `cfg_attr(test, ...)` mock support.
### Removed
- `mock_deps_as`, replaced by `unimock`
- The `entrait_mock_X` procedural macro for multiple-trait-bound mocking.
- The `expand_mock` macro.

## [0.1.0] - 2022-03-07
### Added
- Explicit and opt-in support for `#[async_trait]` with `async_trait = true`.
- Support for `mockall`, with `mockable = true`.
- Support for generating mockall impls for dependencies having multiple trait bounds.

### Changed
- Remove all cargo features. Specific features are now passed as key/value arguments to the macro.
- Split crate into a regular lib and a proc macro crate. `macro_rules` macros and other library functions go in the "outer" `entrait` library.

## [0.0.2] - 2022-02-24
### Changed
- Avoid parsing the full `fn` body. The macro only needs to analyze the signature.

## [0.0.1] - 2022-02-23
### Added
- Basic macro with optional async support using `async-trait`
