Announcing finl_unicode 1.0.0
The first externally useful module of the finl project is now available on crates.io: finl_unicode. This library provides the Unicode handling that finl needs for its parsing module, in particular, it allows checking the character category of a char and getting the next grapheme from Peekable<CharIndices> or Peekable<Chars>. The category determination is roughly ten times faster than the equivalent code in the unicode_categories crate (which is also a bit out of date these days), and the grapheme segmentation runs roughy twice as fast as the unicode_segmentation crate (much to my surprise).
More details are in the readme. available at the crates.io link above.
