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. CamelCase ++2. snake_case ++3. kebab-case ++4. SHOUTY_SNAKE_CASE ++5. mixedCase ++6. Title Case ++7. SHOUTY-KEBAB-CASE ++ ++## Contributing ++ ++PRs of additional well-established cases welcome. ++ ++This library is a little bit opinionated (dropping punctuation, for example). ++If that doesn't fit your use case, I hope there is another crate that does. I ++would prefer **not** to receive PRs to make this behavior more configurable. ++ ++Bug reports & fixes always welcome. :-) ++ ++## MSRV ++ ++The minimum supported Rust version for this crate is 1.32.0. This may change in ++minor or patch releases, but we probably won't ever require a very recent ++version.

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.
