Release 2.1.0 · JelteF/derive_more

Support #[display(rename_all = "<casing>")] attribute to change output for implicit naming of unit enum variants or unit structs when deriving Display. (#443)
Support #[from_str(rename_all = "<casing>")] attribute for unit enum variants and unit structs when deriving FromStr. (#467)
Support Option fields for Error::source() in Error derive. (#459)
Support structs with no fields in FromStr derive. (#469)
Add PartialEq derive similar to std's one, but considering generics correctly, and implementing ne() method as well. (#473, #475)
Add Eq derive similar to std's one, but considering generics correctly. (#479)
Proxy-pass #[allow]/#[expect] attributes of the type in Constructor derive. (#477)
Support Deref and DerefMut derives for enums. (#485)
Support custom error in FromStr derive. (#494)
Support custom error in TryInto derive. (#503)
Support skipping fields in Add-like, AddAssign-like, Mul-like and MulAssign-like derives. (#472)

The minimum supported Rust version (MSRV) is now Rust 1.81. (#466)
Add-like, AddAssign-like, Mul-like and MulAssign-like derives now infer trait bounds for generics structurally (bound field types instead of type parameters directly). (#472)

Suppress deprecation warnings in generated code. (#454)
Silent no-op when #[try_from(repr)] attribute is not specified for TryFrom derive. (#458)
Missing trait bounds in AsRef/AsMut derives when associative types are involved. (#474)
Erroneous code generated in Try/TryInto derives when Self type is present in the struct or enum definition. (#489)
Dependency on unstable feature(error_generic_member_access) in Error derive when using Backtrace on a non-nightly toolchain. (#513)
Broken support for #[<display-trait>("default formatting")] attribute without {_variant} being used as default for enum variants without explicit formatting. (#495)
