Crate limace 

limace

limace is a fast and minimal slugification utility for Rust. It converts strings into clean, URL-friendly slugs using ASCII characters only. It handles Unicode characters via transliteration and supports customizable separator characters.

Features

• Transliterates Unicode to ASCII using deunicode
• Strips punctuation and special characters
• Converts to lowercase
• Customizable separator (default is -)
• No heap allocations beyond the result String

Example

use limace::Slugifier;

fn main() {
    let slugifier = Slugifier::default();

    assert_eq!(slugifier.slugify("Hello, World!"), "hello-world");
    assert_eq!(slugifier.slugify("Crème brûlée"), "creme-brulee");

    let custom = Slugifier::default().with_separator('_');
    assert_eq!(custom.slugify("Hello, World!"), "hello_world");
}

Usage

Add this to your Cargo.toml:

[dependencies]
limace = "0.1"

Then use it in your code:

use limace::Slugifier;

let slug = Slugifier::default().slugify("Rust 2024: Fast & Fearless!");
assert_eq!(slug, "rust-2024-fast-fearless");

Custom separator

You can change the separator using with_separator():

use limace::Slugifier;

let slug = Slugifier::default()
    .with_separator('_')
    .slugify("Hello, World!");
assert_eq!(slug, "hello_world");

How it works

1. Unicode characters are transliterated to ASCII using deunicode_char().
2. Uppercase letters are manually lowercased.
3. Alphanumeric ASCII characters are kept.
4. All other characters are replaced by a separator.
5. Consecutive separators are collapsed into one.
