Random Slug Generator

What it says on the tin - this generates random text slugs in Rust.

Usable as a standalone binary, web applications as a WebAssembly module (WASM), or even as a Python module.

• Rust Binary
• Standalone Binary
• WASM Module
• Python Module

Why?

I needed a way to generate random slugs for a web project so thought it was a good opporunity to try out Rust's WebAssembly capabilities while also being able to use the same code as a zero-dependency python module for other projects.

Key features

• No dependencies
• Fast
• Customisable slug length in words
• Over half a million unique combinations for 2-word slugs ranging up to over 280 trillion unique combinations for 5-word slugs

Usage

As a Rust binary

cargo run --release [length in words] [number of slugs]

As a standalone binary

cargo build --release
[build path]/rustyrs [length in words] [number of slugs]

Example Output

proctor-slimmer-guillemot
unsafe-warlike-avocado
garbled-pulled-stork
answerable-quick-whale
floral-apportioned-bobcat

---

As a WASM module

# If wasm pack is not already installed
cargo install wasm-pack 

# build the WASM module
wasm-pack build --target web --features wasm

Then from JS/TS:

import init, { random_slugs } from './pkg/rustyrs.js';
init();
const slugs: string[] = random_slugs(3, 5);
console.log(slugs);

// slugs: ['postpartum-regal-taipan', 'devastating-elven-salamander', 'immense-ambivalent-wren', 'philosophical-bandaged-gaur', 'outlaw-noncommercial-sunfish']

See index.html for a full example

As a Python module

Install from PyPI

pip install rustyrs

Build from source

python -m venv venv
source venv/bin/activate
pip install maturin
maturin develop --features python

Then from Python:

from rustyrs import random_slugs
slugs: list[str] = random_slugs(3, 5)

# slugs: ['reflecting-unsealed-mamba', 'disabling-addicting-asp', 'pliable-begotten-barnacle', 'vaulting-telepathic-caracal', 'canonical-graven-beetle']

Other features:

• get_slug(word_length: int) -> str: Generate a single slug of a specific length
• SlugGenerator(word_length: int): Create a generator object to generate slugs of a specific length. Can generate slugs infinitely.

  from rustyrs import SlugGenerator
  gen = SlugGenerator(3)
  print(next(gen)) # 'unwieldy-unsuspecting-ant'
  

• combinations(word_length: int) -> int: Get the number of possible combinations for a given word length

  from rustyrs import combinations
  print(combinations(3)) # 556,284
  

Performance

• 1m x 2 word slugs: ~4.995s
• 1m x 5 word slugs: ~10.447s
