uncased 0.9.9

Case-preserving, ASCII case-insensitive, no_std string types.

uncased ‚ÄČ crates.io docs.rs

Case-preserving, ASCII case-insensitive no_std string types.

An uncased string is case-preserving. That is, the string itself contains cased characters, but comparison (including ordering, equality, and hashing) is ASCII case-insensitive.

use uncased::UncasedStr;

let x: &UncasedStr = "hello!".into();
let y: &UncasedStr = "HelLo!".into();

assert_eq!(x, y);
assert_eq!(x.as_str(), "hello!");
assert_eq!(y.as_str(), "HelLo!");

See the documentation for detailed usage information.


Add the following to your Cargo.toml:

uncased = "0.9"

This crate is #![no_std] compatible. By default, the alloc feature is enabled, which enables the Uncased type but requires alloc support. To disable the feature, disable this crate's default features:

uncased = { version = "0.9", default-features = false }

Note: This crate does not perform Unicode case-folding. For Unicode case-folding, see unicase.
