[dependabot]

Bumps darling from 0.21.0 to 0.23.0.

Release notes

Sourced from darling's releases.

v0.23.0

• 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
• Revert dependency version pins which caused problems #385

v0.22.0

YANKED Pinned dependencies made this version cause conflicts with other crates.

• 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

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

v0.21.2

• 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

• 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
