Crate unicode_categories [] [src]

unicode-categories is a crate that adds extensions to the char primitive type that allow for a char to be queried about whether or not it belongs to a particular Unicode category.

These extensions exist on the UnicodeCategories trait, so by importing it the extensions will be active on all chars:

use unicode_categories::UnicodeCategories;

assert!('a'.is_letter_lowercase());
assert!('A'.is_letter_uppercase());
assert!('\n'.is_other_control());

UnicodeCategories is the only item contained exported by this crate and contains all of methods that allow for category queries.
