flecs-dylib-modules

You can hot-reload Flecs systems in Rust by structuring system logic as separate Rust dylibs. This allows runtime module load and unload operations to update systems while preserving existing component data in the ECS world.

The best way to structure Rust dylibs for Flecs ECS hot-reloading is to split code into component-only modules and system modules. System modules import component modules via Cargo dependencies and are compiled as dylibs for runtime loading.

Yes, multiple Flecs system modules can share the same Rust components during hot-reload. By isolating components in their own modules, multiple system dylibs can import and operate on them simultaneously without data loss.

Flecs ECS supports cargo-based dependency management for Rust dylibs by organizing modules into separate crates. System modules declare component modules as cargo dependencies, enabling clean boundaries and runtime load/unload semantics.

Flecs components break during Rust system hot-reloading if components and systems are not separated into distinct modules. Defining components in their own dedicated modules ensures component data persists when system dylibs are unloaded and reloaded.

You need to use Rust dylibs for Flecs ECS modules when you want to update module logic and systems without restarting the Flecs world. This is ideal for ECS projects requiring fast iteration and clean component-system boundaries.
