- Graphemes and GraphemeIndices structs implement iterators over
grapheme clusters analogous to the Chars and CharOffsets for chars in
a string. Iterator and DoubleEndedIterator are available for both.
- tidied up the exports for libunicode. crate root exports are now moved
into more appropriate module locations:
- UnicodeStrSlice, Words, Graphemes, GraphemeIndices are in str module
- UnicodeChar exported from char instead of crate root
- canonical_combining_class is exported from str rather than crate root
Since libunicode's exports have changed, programs that previously relied
on the old export locations will need to change their `use` statements
to reflect the new ones. See above for more information on where the new
exports live.
