Release Notes

JelteF/derive_more (derive_more)

v2.1.0

Compare Source

Added

• 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)

Changed

• 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)

Fixed

• 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)
