 # Change Log
 All notable changes to this project will be documented in this file.
 This project adheres to [Semantic Versioning](http://semver.org/).

 ## [0.20.1] - 2024-08-28
 - Forward default type params #319

 ## [0.20.0] - 2024-02-14
 - Bump `syn` to version 2 #308
 - Bump `darling` to version 0.20.6 #308
 - **BREAKING CHANGE**: Remove support for `field(type = "...")` as `syn` no longer allows this. #308
 - Allow omitting quotes on `builder(default = ...)` expressions #308

 ## [0.13.1] - 2024-02-12
 - Accept `field(ty = "...")` as an alias for `field(type = "...")` in preparation for moving to syn 2.0, which doesn't allow the use of keywords as meta item paths. #306

 ## [0.13.0] - 2024-01-22
 - Bump MSRV to 1.56.0
 - Add `build_fn(error(validation_error = <bool>))` to disable generation of `ValidationError` within the builder's error so that `alloc::string` is avoided.
 - Add feature `alloc` for controlling linking of `alloc` crate during `no_std`. This way users can use `no_std` without providing a `global_allocator`.
 - Make try-setters inherit `strip_option` from `setter` for `try_setter`. Using these settings together previously caused a compile error  #284

 ## [0.12.0] - 2022-11-28

 ## [0.11.2] - 2022-04-20
 - Allow restricted visibility using `vis = "..."` for builders, build methods, setters, and fields #247
 - Allow specifying the type of a builder field using `#[builder(field(type = "..."))]` #246
 - Allow specifying how a builder field is built using `#[builder(field(build = "..."))]` #246
 - Update `darling`, `proc-macro2`, `syn`, and `quote` dependencies #250

 ## [0.11.1] - 2022-03-16
 - Forward `allow` and `cfg` attributes from the deriving struct to the builder and its impl block #222
 - Support passing attributes to the builder struct using `#[builder_struct_attr(...)]`
 - Support passing attributes to the builder struct's inherent `impl` block using `#[builder_impl_attr(...)]`

 ## [0.11.0] - 2022-03-15
 - Support shorthand and long-form collection setters; `#[builder(setter(each = "..."))]` and `#[builder(setter(each(name = "...")))]` #234
 - Allow collection setters to be generic over `Into` using `#[builder(setter(each(name = "...", into)))] #234 and #214

 ## [0.8.0] - 2019-09-30
 - Increase dependency versions to latest #148
 - Requires Rust 1.37.0 or newer (was 1.18.0) #148

 ## [0.7.0] - 2018-10-22

 ### Breaking Changes
 - Updated all dependencies to latest versions #138

 ## [0.6.0] - 2018-09-04

 ### Breaking Changes
 - Requires Rust 1.18.0 or newer (was 1.15.0) #120
 - Updated to `syn` 0.13.10. #120
 - Updated to `quote` 0.5.2 #120
 - Removed support for deprecated attributes #120

 ### Changed
 - `Clone` is no longer derived on a builder using the owned pattern unless it
   has a field override that uses the mutable/immutable pattern. #97
 - Using `#[builder(private)]` at the struct level will now emit a private builder. #99

 ### Added
 - Use `build_fn(private)` to generate a build method only accessible within the mod scope #89

 ### Internal Changes
 - Rewrote options parser using `darling` 0.6.3 #120

 ## [0.5.2] - 2018-05-31

 ### Fixed
 - Generated code for structs with type parameters and struct-level defaults now compiles #127

 ## [0.5.1] - 2017-12-16

 ### Changed
 - The standard library `collections` crate was merged into `alloc`
   ([PR](https://github.com/rust-lang/rust/pull/42648)).
   Correspondingly when using this crate within a crate with `#![no_std]` you must
   use `#![feature(alloc)] extern crate alloc` in your crate,
   was `#![feature(collections)] extern crate collections`.

 ### Fixed
 - `unused_mut` lint (variable does not need to be mutable) #104

 ## [0.5.0] - 2017-06-30

 ### Changed

 - `#[builder(default)]` and `#[builder(default = "...")]` at the struct level
   change their behaviour and construct a default value for the struct,
   instead of all fields individually.
 - builder fields are no longer public by default; Fields can be explicitly
   made public at the struct or field level using the new attribute:
   `#[builder(field(public))]`

 ### Removed
 - removed previously deprecated syntax `#[builder(setter_prefix = "with")]`,
   please use `#[builder(setter(prefix = "with"))]` instead

 ## [0.4.7] - 2017-04-29

 ### Fixed
 - for generic structs, apply the `T: Clone` type bound in builder impl
   instead of struct definition #91
 - only emit the `T: Clone` type bound when it is actually needed, i.e.
   mutable/immutable pattern, but not owned pattern.

 ## [0.4.6] - 2017-04-26

 ### Added
 - pre-build validation via `#[builder(build_fn(validate = "path::to::fn"))]`

 ## [0.4.5] - 2017-04-25

 ### Added
 - customize setter names via `#[builder(setter(name = "..."))]`
 - customize build_fn name via `#[builder(build_fn(name = "..."))]`
 - suppress build method generation via `#[builder(build_fn(skip))]`
 - derive additional traits via `#[builder(derive(Trait1, Trait2, ...))]`
 - set field visibility separate from setter visibility via
   `#[builder(field(private))]` at the field or struct level

 ### Deprecated
 - builder fields will no longer be public by default in 0.5.0; relying on this
   will now emit a deprecation warning. Fields can be explicitly made public at
   the struct or field level using the new `#[builder(field(public))]`
   attribute. To squelch this warning and opt-into the new behaviour, use the
   `private_fields` crate feature or explicitly set field visibility at the
   struct level.

 ## [0.4.4] - 2017-04-12

 ### Added
 - try_setters, e.g. `#[builder(try_setter)]`. These setters are exposed
   alongside the normal field setters and allow callers to pass in values which
   have fallible conversions to the needed type through `TryInto`. This
   attribute can only be used on nightly when `#![feature(try_from)]` is
   declared in the consuming crate's root; this will change when Rust issue
   [#33417](https://github.com/rust-lang/rust/issues/33417) is resolved.

 ## [0.4.3] - 2017-04-11

 ### Fixed
 - `setter(skip)` honors struct-inherited and explicit defaults #68

 ## [0.4.2] - 2017-04-10

 ### Fixed
 - support generic references in structs #55
 - support `#![no_std]` #63

 ## [0.4.1] - 2017-04-08

 ### Deprecated
 - `#[builder(default)]` and `#[builder(default = "...")]` at the struct level will
   change their behaviour in 0.5.0 and construct a default value for the struct,
   instead of all fields individually. To opt into the new behaviour and squelch
   this deprecation warning you can add the `struct_default` feature flag.

 ## [0.4.0] - 2017-03-25

 ### Added
 - skip setters, e.g. `#[builder(setter(skip))]`
 - default values, e.g. `#[builder(default = "42")]` or just `#[builder(default)]`

 ### Changed
 - deprecated syntax `#[builder(setter_prefix = "with")]`,
   please use `#[builder(setter(prefix = "with"))]` instead
 - setter conversions are now off by default, you can opt-into via
   `#[builder(setter(into))]`
 - logging is behind a feature flag. To activate it, please add
   `features = ["logging"]` to the dependency in `Cargo.toml`. Then you can use
   it like: `RUST_LOG=derive_builder=trace cargo test`.

 ### Fixed
 - use full path for result #39
 - support `#[deny(missing_docs)]` #37
 - support `#![no_std]` via `#[builder(no_std)]` #41

 ## [0.3.0] - 2017-02-05

 Requires Rust 1.15 or newer.

 ### Added
 - different setter pattern, e.g. `#[builder(pattern = "immutable")]`
 - private setters, e.g. `#[builder(private)]`
 - additional debug info via env_logger, e.g.
   `RUST_LOG=derive_builder=trace cargo test`
 - prefixes, e.g. `#[builder(setter_prefix = "with")]`
 - field specific overrides
 - customize builder name, e.g. `#[builder(name = "MyBuilder")]`

 ### Changed
 - migration to macros 1.1
 - migration to traditional builder pattern
   i.e. seperate `FooBuilder` struct to build `Foo`
 => please refer to the new docs

 ### Fixed
 - missing lifetime support #21

 ## [0.2.1] - 2016-09-24

 ### Fixed
 - preserve ordering of attributes #27

 ## [0.2.0] - 2016-08-22
 ### Added
 - struct fields can be public
 - struct fields can have attributes
 - the following struct-attributes are copied to the setter-method
  - `/// ...`
  - `#[doc = ...]`
  - `#[cfg(...)]`
  - `#[allow(...)]`

 ### Changed
 - setter-methods are non-consuming now -- breaking change
 - setter-methods are public now

 ### Fixed
 - automatic documentation does not work #16

 ## [0.1.0] - 2016-08-07
 ### Added
 - first implementation
  - generate setter methods
  - support for generic structs
