hecs

hecs provides a high-performance, minimalist entity-component-system (ECS) world. It is a library, not a framework. In place of an explicit "System" abstraction, a World's entities are easily queried from regular code. Organize your application however you like!

Other Libraries

hecs would not exist if not for the great work done by others to introduce and develop the ECS paradigm in the Rust ecosystem. In particular:

• specs played a key role in popularizing ECS in Rust
• legion reduced boilerplate and improved cache locality with sparse components

hecs builds on these successes by focusing on further simplification, boiling the paradigm down to a minimal, light-weight and ergonomic core, without compromising on performance or flexibility.
