Unreleased

0.0.9 - 2024-12-02

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!

0.0.8 - 2024-07-07

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

0.0.7 - 2024-04-09

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())

0.0.6 - 2023-04-08
