| |
| - Add `Clone` impl for `NestedMeta` [#230](https://github.com/TedDriggs/darling/pull/230) |
| |
| ## v0.20.0 (April 27, 2023) |
| |
| - Bump syn to version 2, courtesy of @jonasbb [#227](https://github.com/TedDriggs/darling/issues/227) |
| |
| ### Breaking Changes |
| |
| - Replace all occurrences of syn::NestedMeta with darling::ast::NestedMeta. |
| |
| - Replacement for the deprecated AttributeArgs: |
| |
| ```rust |
| // Before |
| |
| parse_macro_input!(args as AttributeArgs); |
| |
| // After |
| |
| match NestedMeta::parse_meta_list(args) { |
| Ok(v) => v, |
| Err(e) => { |
| return TokenStream::from(Error::from(e).write_errors()); |
| } |
| }; |
| ``` |
| |
| - In GenericParamExt, `LifetimeDef` is now `LifetimeParam`. |
| - In GenericParamExt, `as_lifetime_def` is renamed to `as_lifetime_param`. |
| - Flag and SpannedValue no longer implement `syn::spanned::Spanned`. |
| - The MSRV (minimum supported Rust version) is now 1.56, because of syn. |
| |
| ### Deprecation Warnings |
| |
| In previous versions of `darling`, arbitrary expressions were passed in attributes by wrapping them in quotation marks. |
| v0.20.0 preserves this behavior for `syn::Expr`, but as a result a field expecting a `syn::Expr` cannot accept a string literal - it will incorrectly attempt to parse the contents. If this is an issue for you, please add a comment to [#229](https://github.com/TedDriggs/darling/issues/229). |
| |
| ## v0.14.4 (March 9, 2023) |
| |
| - Add support for child diagnostics when `diagnostics` feature enabled [#224](https://github.com/TedDriggs/darling/issues/224) |
| |
| ## v0.14.3 (February 3, 2023) |
| |
| - Re-export `syn` from `darling` to avoid requiring that consuming crates have a `syn` dependency. |
| - Change `<SpannedValue<T> as FromMeta>` impl to more precisely capture the _value_ span, as opposed to the span of the entire item. |
| - Add `darling::util::{AsShape, Shape, ShapeSet}` to improve "shape" validation for structs and variants. [#222](https://github.com/TedDriggs/issues/222) |
| |
| ## v0.14.2 (October 26, 2022) |
| |
| - Derived impls of `FromMeta` will now error on literals, rather than silently ignoring them. [#193](https://github.com/TedDriggs/darling/pull/193) |
| - Don't include property paths in compile errors when spans are available. [#203](https://github.com/TedDriggs/darling/pull/203) |
| |
| ## v0.14.1 (April 28, 2022) |
| |
| - Fix a bug where using a trait that accepts `#[darling(attributes(...))]` without specifying any attributes would emit code that did not compile. [#183](https://github.com/TedDriggs/darling/issues/183) |
| - Impl `Clone` for `darling::Error` [#184](https://github.com/TedDriggs/darling/pull/184) |

| |
| ## v0.14.0 (April 13, 2022) |
| |
| - **BREAKING CHANGE:** Remove many trait impls from `util::Flag`. |
| This type had a number of deref and operator impls that made it usable as sort-of-a-boolean. |
| Real-world usage showed this type is more useful if it's able to carry a span for good errors, |
| and that most of those impls were unnecessary. [#179](https://github.com/TedDriggs/darling/pull/179) |
| - Remove need for `#[darling(default)]` on `Option<T>` and `Flag` fields [#161](https://github.com/TedDriggs/darling/issues/161) |
| - Improve validation of enum shapes [#178](https://github.com/TedDriggs/darling/pull/178) |

| - Impl `FromMeta` for `syn::Type` and its variants [#172](https://github.com/TedDriggs/darling/pulls/172) |
| |
| ## v0.13.2 (March 30, 2022) |
| |
| - Impl `FromMeta` for `syn::ExprPath` [#169](https://github.com/TedDriggs/darling/issues/169) |
| |

| |
| - Add `FromAttributes` trait and macro [#151](https://github.com/TedDriggs/darling/issues/151) |

| |
| - Update darling to 2018 edition [#129](https://github.com/TedDriggs/darling/pull/129) |
| - Error on duplicate fields in `#[darling(...)]` attributes [#130](https://github.com/TedDriggs/darling/pull/130) |
| |
| ## v0.12.4 (April 20, 2021) |
| |
| - Add `and_then` to derive macros for `darling` |
| |
| ## v0.12.3 (April 8, 2021) |
| |

| |

| - Add `darling::ast::Data::try_empty_from` to avoid panics when trying to read a union body [#123](https://github.com/TedDriggs/darling/pull/123) |
| |
| ## v0.12.0 (January 5, 2021) |
| |
| - POSSIBLY BREAKING: Derived impls of `FromDeriveInput`, `FromField`, `FromVariant`, and `FromTypeParam` will now error when encountering an attribute `darling` has been asked to parse that isn't a supported shape. |
| Any crates using `darling` that relied on those attributes being silently ignored could see new errors reported in their dependent crates. [#113](https://github.com/TedDriggs/darling/pull/113) |
| - Impl `syn::spanned::Spanned` for `darling::util::SpannedValue` [#113](https://github.com/TedDriggs/darling/pull/113) |
| - Add `darling::util::parse_attribute_to_meta_list` to provide useful errors during attribute parsing [#113](https://github.com/TedDriggs/darling/pull/113) |
