roe
Implements Unicode case mapping for conventionally UTF-8 binary strings.
Case mapping or case conversion is a process whereby strings are converted to a particular form—uppercase, lowercase, or titlecase—possibly for display to the user.
roe
can convert conventionally UTF-8 binary strings to capitalized, lowercase,
and uppercase forms. This crate is used to implement String#capitalize
,
Symbol#capitalize
, String#downcase
, Symbol#downcase
,
String#upcase
, and Symbol#upcase
in Artichoke Ruby.
This crate depends on bstr
.
Status
This crate is currently a work in progress. When the API is complete, Roe will support lowercase, uppercase, titlecase, and case folding iterators for conventionally UTF-8 byte slices.
Roe will implement support for full, Turkic, ASCII, and case folding transforms.
Usage
Add this to your Cargo.toml
:
[]
= "0.0.5"
Then convert case like:
use ;
assert_eq!;
assert_eq!;
