A Rust developer forked the popular rand crate to create urandom, a randomness library with a simplified, unified API centered around a single Random wrapper struct. The author argues that rand's multi-trait extension method design makes common operations hard to discover, while urandom consolidates methods like uniform, choose, shuffle, and sample as inherent methods on one type.
Background
The rand crate is the most widely used randomness library in the Rust ecosystem, providing RNGs, distributions, and sequence operations. This fork represents a design philosophy debate around API discoverability versus flexibility in Rust library design.
