Unreleased

1.1.0 - 2019-11-03

Added

• assert_impl_any! macro
• assert_impl_one! macro
• assert_trait_sub_all! macro
• assert_trait_super_all! macro
• Frequently asked questions to README.md

Fixed

• assert_eq_size_val!, const_assert_eq!, and const_assert_ne! to export their local inner macros. Not having this prevented them from working when used or called directly via static_assertions::macro!(...)

Removed

• Unused _assert_obj_safe! from pre-1.0

1.0.0 - 2019-10-02

Added

• assert_eq_align! macro

Removed

• [breaking] Labels from macros that needed them 🎉
  • Made possible by const _ in Rust 1.37
• [breaking] assert_impl! macro

Fixed

• assert_fields! now works for enum types with multiple variants

Changed

• [breaking] const_assert! macro to only take one expression
  • Reasoning: when custom error messages are added in the future (via assert!), having the macro allow for multiple comma-separated expressions may lead to ambiguity
• [breaking] Trait assertions to use Type: Trait syntax
• [breaking] Field assertions to use Type: field1, field2 syntax
• [breaking] Renamed assert_{ne,eq}_type! to assert_type_{ne,eq}_all!

0.3.4 - 2019-06-12

Changed

• Aliased assert_impl! to assert_impl_all! and deprecated assert_impl!

Added

• assert_impl_all! as replacement to assert_impl!
• assert_not_impl_all! and assert_not_impl_any! macro counterparts to assert_impl_all!

Fixed

• assert_eq_type! now works with types involving lifetimes

0.3.3 - 2019-06-12

Added

• const_assert_ne! macro counterpart to const_assert_eq!

Fixed

• assert_eq_type! would pass when types can coerce via Deref, such as with str and String

0.3.2 - 2019-05-15

Added

• A assert_eq_type! macro that allows for checking whether inputs are the same concrete type
• A assert_ne_type! macro for checking whether inputs all refer to different types

Fixed

• const_assert! now only takes bool values whereas integer (or other type) values could previously be passed

0.3.1 - 2018-11-15

Fixed

• Macros that refer to other internal macros can now be imported when compiling for Rust 2018 (issue #10)

0.3.0 - 2018-11-14

Changed

• Bumped minimum supported (automatically tested) Rust version to 1.24.0
• Moved message parameter for assert_cfg!() to last argument position, making it consistent with other macros

Removed

• No need to use macro!(label; ...) syntax when compiling on nightly Rust and enabling the nightly feature flag

0.2.5 - 2017-12-12

Changed

• assert_eq_size_ptr wraps its code inside of a closure, ensuring that the unsafe code inside never runs
• Clippy no longer warns about unneeded_field_pattern within assert_fields

Added

• Much better documentation with test examples that are guaranteed to fail at compile-time

Removed

• Removed testing features; compile failure tests are now done via doc tests

0.2.4 - 2017-12-11

Removed

• Removed the actual call to mem::transmute while still utilizing it for size verification (Simon Sapin, #5)

Added

• assert_cfg macro that asserts that the given configuration is set
• assert_fields macro to assert that a struct type or enum variant has a given field

Fixed

• Allow more generics flexibility in assert_impl

0.2.3 - 2017-08-24

Fixed

• Trailing commas are now allowed

Removed

• Removed clippy warnings

0.2.2 - 2017-08-13

Added

• Added assert_impl macro to ensure a type implements a given set of traits

0.2.1 - 2017-08-13

Added

• Added assert_obj_safe macro for ensuring that a trait is object-safe

0.2.0 - 2017-08-12

Added

• Added assert_eq_size_ptr macro

Fixed

• Allow assert_eq_size, const_assert, and const_assert_eq in non-function contexts via providing a unique label #1

Removed

• [Breaking] Semicolon-separated assert_eq_size is no longer allowed

0.1.1 - 2017-08-12

Added

• Added const_assert_eq macro

0.1.0 - 2017-08-12
