Release Notes

asomers/mockall (mockall)

v0.12.0

Compare Source

Added

• Added #[mockall::concretize], which can be used to mock some generic
  methods that have non-'static generic parameters. It works by turning the
  generic arguments into trait objects for the expectation.
  (#​408)

• When mocking functions with a non-default ABI (Like extern "C"), the mock
  function will now use the same ABI as the original. Name mangling will also
  be disabled, so the mock function will be callable from external code. For
  example, from C functions.
  (#​504)

Changed

• Raised predicates, which is reexported, to 3.0.0. This may affect backwards
  compatibility for users who make use of predicates's "color" feature.
  (#​467)

• Raised MSRV to 1.64.0 because predicates-core and predicates-tree did.
  (#​430)
  (#​467)

• Better "No matching expectation found" messages on stable.
  (#​425)

Fixed

• Fixed mocking non-private inherent methods that have attributes with syn
  version 2.0.9 and later.
  (#​486)

• Suppress clippy::too_many_arguments warnings in the generated code. This
  is most useful when mocking static functions with exactly 7 arguments.
  (#​487)

• Fixed unused_attributes warnings in the generated code when mocking FFI
  functions that use #[link_name].
  (#​503)

• Fix a panic during Drop for static methods. One way to trigger it is by
  calling the method more times than is allowed by a .times() constraint.
  Another way would be to explicitly panic during the .returning method.
  (#​516)

Removed

• Removed syntax deprecated since 0.9.0: using #[automock] directly on an
  extern "C" block, and using trait Foo {} syntax inside of mock!.
  (#​476)

• Removed default features from predicates dependency. Reexports no longer
  include difflib, normalize-line-endings, regex and float-cmp features.
  (#​517)
