hecs is a fast, minimalist entity-component-system (ECS) library for Rust that provides a World of entities queried from regular code without imposing a framework or System abstraction. It stores components in dense, contiguous arrays for cache-friendly linear traversals.

Use cases

• build a game with an entity-component-system architecture in Rust
• manage large collections of entities with loosely-coupled component data
• query entities by component types with fast cache-friendly iteration
• add new behaviors to existing objects without refactoring class hierarchies
• use a lightweight ECS inside an existing engine or application

When to choose

• you want a minimal, ergonomic ECS library rather than a full game framework
• you need high-performance, cache-friendly component iteration
• you prefer organizing your own systems in plain Rust code
• you want near-zero boilerplate when defining components

When to avoid

• you need a full game engine with rendering, audio, and asset management built in
• you want scheduler features, system dependency graphs, or parallel system execution out of the box
• you need archetype-level reflection or serialization tooling beyond the basics
