Upgrade rust/crates/heck to 0.3.2 Test: make Change-Id: Id659f4bce25cd296ce8bc27c633db12b47da1f6f
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.
Word boundaries are defined as the “unicode words” defined in the unicode_segmentation
library, as well as within those words in this manner:
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.
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. :-)
