0.3.0

Breaking changes

• Take self rather than &mut self for UniqueMmioPointer::split. The old behaviour can be
  achieved by calling reborrow first.
• Take self rather than &self for SharedMmioPointer::split. SharedMmioPointer is Copy so
  this should make no difference in most cases.

Improvements

• Added modify and modify_mut methods to UniqueMmioPointer<ReadWrite<T>> and
  UniqueMmioPointer<ReadPureWrite<T>>.
• Added get_range() methods to UniqueMmioPointer<[T]>, UniqueMmioPointer<[T; LEN]>,
  SharedMmioPointer<[T]>, SharedMmioPointer<[T; LEN]>. These methods return a pointer to the
  subset of elements, specified by a Range.
• Added iter() methods to UniqueMmioPointer<[T]>, UniqueMmioPointer<[T; LEN]>,
  SharedMmioPointer<[T]>, SharedMmioPointer<[T; LEN]>. These methods return an iterator to the
  items of the pointer slices or arrays.

0.2.7

Improvements

• Added UniqueMmioPointer::split_some for arrays and slices.

0.2.6

Improvements

• Optimised implementation of From<UniqueMmioPointer<[T; LEN]>> for [UniqueMmioPointer<T>; LEN].

0.2.5

Improvements

• Added UniqueMmioPointer::take for arrays and slices, similar to get but taking ownership of
  the original pointer rather than borrowing it.
• Added implementation of From to convert from pointer to array to array of pointers.
• Implemented Copy for SharedMmioPointer.
• Extended lifetimes of values returned from SharedMmioPointer::as_slice,
  SharedMmioPointer::get, SharedMmioPointer::split and field_shared!. They are now tied only
  to the lifetime parameter of the original SharedMmioPointer, not the lifetime of the reference.

0.2.4

Improvements

• Added UniqueMmioPointer::as_mut_slice and SharedMmioPointer::as_slice to convert from array
  pointer to slice pointer.
• Added implementations of From to convert from array pointers to slice pointers.
• Added implementations of From to convert from pointers to T to pointers to [T; 1] or [T].
• Added split_fields! macro to split a UniqueMmioPointer to a struct into several
  UniqueMmioPointers to its fields.

0.2.3

Improvements

• Made many methods const, in particular:
  • PhysicalInstance::new
  • PhysicalInstance::pa
  • SharedMmioPointer::child
  • SharedMmioPointer::get
  • SharedMmioPointer::new
  • SharedMmioPointer::ptr
  • UniqueMmioPointer::child
  • UniqueMmioPointer::get
  • UniqueMmioPointer::new
  • UniqueMmioPointer::ptr_mut
  • UniqueMmioPointer::ptr_nonnull
• Fixed field! and field_shared! to allow getting unsized fields (e.g. slices) of structs.
• Added UniqueMmioPointer::reborrow.

0.2.2

Bugfixes

• Implemented KnownLayout for ReadPureWrite. This was missed accidentally before.

0.2.1

New features

• Added get method to UniqueMmioPointer<[T; N]> and SharedMmioPointer<[T; N]>.

0.2.0

Breaking changes

• Renamed OwnedMmioPointer to UniqueMmioPointer.

New features

• Added SharedMmioPointer for an MMIO pointer that is not necessarily unique. Unlike a
  UniqueMmioPointer, a SharedMmioPointer can be cloned. UniqueMmioPointer derefs to
  SharedMmioPointer and can also be converted to it.
• Added get and split methods on UniqueMmioPointer<[T]> and UniqueMmioPointer<[T; _]>
  respectively, to go from a pointer to a slice or field to pointers to the individual elements.
• Added field! and field_shared! macros to go from a pointer to a struct to a pointer to an
  individual field.
• Added write_unsafe and read_unsafe methods on UniqueMmioPointer and SharedMmioPointer.
  These call write_volatile and read_volatile on most platforms, but on aarch64 are implemented
  with inline assembly instead to work around
  a bug with how volatile writes and reads are implemented.
• Added wrapper types ReadOnly, ReadPure, WriteOnly, ReadWrite and ReadPureWrite to
  indicate whether a field can safely be written or read (with or without side-effects). Added safe
  write and read methods on UniqueMmioPointer or SharedMmioPointer for these.

0.1.0
