Changelog

0.3.0

Change the API of try_* functions on Parc and Prc to take functions returning Result instead of Option and make them return Result instead of Option.

0.2.3

Factor out the vtable to be shared between the sync and prc modules, as the type definition is identical
Fix tests that should fail and check that we're failing for the right reason on nightly
Remove lifetime bounds from Parc and Prc signatures where the default lifetime bounds are otherwise identical
Improve internal naming of structures and their fields
Increase test coverage to cover as much as possible

0.2.2

Switch TypeErasedArc and TypeErasedRc to use ManuallyDrop when converting the raw pointer into a concrete Arc<T>, Rc<T> or Weak<T> to avoid incorrect behavior in case any method we call panics. Previously, the temporary would be dropped even if it shouldn't have, causing potential UB (use after free).
Add Prc::try_from_rc, Prc::try_project, Parc::try_from_arc, and Parc::try_project. These are fallible versions of the same methods without try_, where the FnOnce that's passed to these functions returns an Option. This allows for using Prc and Parc where the projected reference might be unavailable.

0.2.1

Fix incorrect lifetime bounds on Prc::from_rc and Parc::from_arc.

0.2.0

Fix the soundness issue from 0.1.0 by requiring that any T returned by any projecting function is T: 'static. This change technically restricts the types we can use with Prc and Parc, but doesn't interfere with any intended usage of the crate.

(yanked due to flipped bounds on project functions causing a soundness hole)

0.1.0

Initial release.

(yanked due to a soundness hole where it was possible to use a reference to a reference that didn't live long enough)
