This library exists to provide case conversion between common cases like -//! CamelCase and snake_case. It is intended to be unicode aware, internally -//! consistent, and reasonably well performing. -//! -//! ## Definition of a word boundary -//! -//! Word boundaries are defined as the "unicode words" defined in the -//! `unicode_segmentation` library, as well as within those words in this -//! manner: -//! -//! 1. All underscore characters are considered word boundaries. -//! 2. If an uppercase character is followed by lowercase letters, a word -//! boundary is considered to be just prior to that uppercase character. -//! 3. If multiple uppercase characters are consecutive, they are considered to -//! be within a single word, except that the last will be part of the next word -//! if it is followed by lowercase characters (see rule 2). -//! -//! That is, "HelloWorld" is segmented `Hello|World` whereas "XMLHttpRequest" is -//! segmented `XML|Http|Request`. -//! -//! Characters not within words (such as spaces, punctuations, and underscores) -//! are not included in the output string except as they are a part of the case -//! being converted to. Multiple adjacent word boundaries (such as a series of -//! underscores) are folded into one. ("hello__world" in snake case is therefore -//! "hello_world", not the exact same string). Leading or trailing word boundary -//! indicators are dropped, except insofar as CamelCase capitalizes the first -//! word. -//! -//! ### Cases contained in this library: -//! -//! 1. UpperCamelCase -//! 2. lowerCamelCase -//! 3. snake_case -//! 4. kebab-case -//! 5. SHOUTY_SNAKE_CASE -//! 6. Title Case -//! 7. SHOUTY-KEBAB-CASE -//! 8.
