0.2.1 Release

[0.2.1] - 2020-01-24

Added

• The feature "packed-headers" can be enabled for an experimental object layout featuring reduced header size.
• Further improved documentation.

Changed

• Deprecated the confusing MutEntry::{as_ref, as_mut_ref}; Use {get, get_mut} instead

0.2.0 Release

Added

• Added an optional feature to enable debugging index validity at the cost of efficiency
  • Accesses to regions will be checked and give correct errors
  • Validity will be checked during GC
  • This has a dramatic increase in space cost, and a small overhead in time.
• Ix supports an identifier method, which returns a usize,
  unique for the current region/generation
• Added and improved documentation in several places

Changed

• Separated Weak and Root into two different types.
  • Weak.ix() now returns Option<Ix>, which can be used to test
    if it's been collected
• MutEntry::to_root is now MutEntry::root and no longer takes ownership

Fixed

• Creating a weak and root pointer to the same entry would cause Weak pointers
  to act like roots.
