v0.0.10

Added

• Wrapper<T> trait added for creating wrapper structs with a structurally pinned value.
• MaybeZeroable derive macro to try to derive Zeroable, but not error if not all fields
  implement it.
• unsafe fn cast_[pin_]init() functions to unsafely change the initialized type of an initializer
• impl<T, E> [Pin]Init<T, E> for Result<T, E>, so results are now (pin-)initializers
• add Zeroable::init_zeroed() delegating to init_zeroed()
• add new zeroed(), a safe version of mem::zeroed() and also provide it via Zeroable::zeroed()
• implement Zeroable for Option<&T> and Option<&mut T>
• implement Zeroable for Option<[unsafe] [extern "abi"] fn(...args...) -> ret> for "Rust" and
  "C" ABIs and up to 20 arguments

Changed

• InPlaceInit now only exists when the alloc or std features are enabled
• added support for visibility in Zeroable derive macro
• added support for unions in Zeroable derive macro
• renamed the crate from pinned-init to pin-init and pinned-init-macro to pin-init-internal
• blanket impls of Init and PinInit from impl<T, E> [Pin]Init<T, E> for T to
  impl<T> [Pin]Init<T> for T
• renamed zeroed() to init_zeroed()

Fixed

• Zeroable implementation for Option<Box<T>> & Option<NonNull<T>> to only allow T: Sized
  (soundness issue)

  Full changes: v0.0.9...v0.0.10

v0.0.9

Added

• InPlaceWrite trait to re-initialize already existing allocations,
• assert_pinned! macro to check if a field is marked with #[pin],
• compatibility with stable Rust, thanks a lot to @bonzini! #24 and #23:
  • the alloc feature enables support for allocator_api and reflects the old behavior, if it is
    disabled, then infallible allocations are assumed (just like the standard library does).

Fixed

• guard hygiene wrt constants in [try_][pin_]init!

Full changes: v0.0.8...v0.0.9

v0.0.8

Changed

• return type of zeroed() from impl Init<T, E> to impl Init<T> (also removing the generic
  parameter E)
• removed the default error of try_[pin_]init!, now you always have to specify an error using
  ? Error at the end
• put InPlaceInit behind the alloc feature flag, this allows stable usage of the #![no_std]
  part of the crate

Full changes: v0.0.7...v0.0.8

v0.0.7

Added

• Zeroable derive macro
• ..Zeroable::zeroed() tail expression support in [try_][pin_]init! macros: allowed to omit
  fields, omitted fields are initialized with 0
• [pin_]chain functions to modify a value after an initializer has run
• [pin_]init_array_from_fn to create impl [Pin]Init<[T; N], E> from a generator closure
  fn(usize) -> impl [Pin]Init<T, E>
• impl Zeroable for UnsafeCell

Changed

• PinInit is now a supertrait of Init (before there was a blanket impl)

Removed

• coverage workflow and usage of #[feature(no_coverage)]
• impl Zeroable for Infallible (see Security)

Fixed

• Self in generic bounds on structs with #[pin_data]
• const generic default parameter values can now be used on structs with #[pin_data]

Security

• impl Zeroable for Infallible (#13) it was possible to trigger UB by creating a value of type
  Box<Infallible> via Box::init(zeroed())
