Release Notes

TedDriggs/darling (darling)

v0.23.0

Compare Source

• Bump MSRV to 1.88.0; there have been no code changes that caused this, but due to dependency issues CI no longer works on 1.56.0 #​357

v0.22.0

Compare Source

• BREAKING: Remove fnv dependency, as runtime performance gain does not justify additional dependency. This was exposed to users of darling::usage, so it may be breaking for them #​373
• Add #[darling(default = || expr(val))] support, allowing a closure where a path was previously required #​380
• Preserve span information for paths given to darling::util::Callable as literal strings
• Fix some documentation typos

v0.21.3

Compare Source

• Fix: Forward Override::<T>::from_expr to T::from_expr #​371

v0.21.2

Compare Source

• Add #[darling(from_expr = ...)] when deriving FromMeta to support overriding the key-value form #​369
• Keep parsing the body and type params even if there are errors from parsing attributes. #​7
• Support #[darling(with = ...)] on the generics field when deriving FromDeriveInput.
• Return an error, rather than panicking, when doing shape validation on a union. #​365

v0.21.1

Compare Source

• Track all alternate field names, and show them in error message if there aren't too many. #​325
• Track all alternate values for enum variants, and show them in error messages if there aren't too many. #​362

v0.21.0

Compare Source

• Potentially breaking: Emit error when an attribute path is present in both attributes and forward_attrs. #​336
• Support parsing attributes which contain keywords #​238
• Add SpannedValue::into_inner #​342
• Add #[darling(derive_syn_parse)] to also impl syn::parse::Parse when deriving FromMeta #​285
• Make impl FromMeta for syn::TypePath support both quote-wrapped and bare values #​351
• Add util::PreservedStrExpr #​346
• Impl UsesTypeParams and UsesLifetimes for WithOriginal #​215
• Update error message emitted by <() as FromMeta>::from_list to allow use of () as a #[darling(flatten)] target #​353
