typed_ecs

A no_std and no-alloc tiny ECS written in Rust, which provides strong compile-time guarantees.

This project is in active development but is ready to be used, just note that its API will break often until v0.1.x releases.

About

typed_ecs is a tiny, zero-cost framework that:

• lets you wire plugins together at compile time using tuple-based plugin lists
• enforces plugin / shared-data compatibility via Rust trait bounds (no runtime checking)
• is written for no_std and no_alloc environments (small, deterministic runtime)

Key features

• no_std compatible, and no-alloc: all kinds of platforms supported
• Compile-time plugin composition
• Strong compile-time guarantees for plugin/SharedData compatibility
• Zero runtime-registration or reflection — everything resolved at compile time
• Light, optimized runtime loop, with direct plugin calls
• Ergonomic design: no tricky or cryptic code needed to use typed_ecs
