🦀 a list of (mostly) zero dependency libraries for Rust

Minimal Rust

This is a list of Rust libraries which have zero, one, or two total dependencies with default-features = false, as reported by cargo tree.

Some of these trade dependencies for completeness, meaning they have a limited amount of features compared to their more well-known cousins, while some of these are the more well-known cousins and are listed because they already have minimal dependencies, like memchr.

For a great list of major Rust crates without any pedantry around dependencies:
