Bumps derive_more from 2.0.1 to 2.1.0.

Release notes

Sourced from derive_more's releases.

2.1.0

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)
