You'll find a very good introduction to ECS in Rust in the book "Hands-on Rust: Effective learning through 2D Game Development"¹. It's based on Legion, which (AFAIK) is now discontinued, but the book/project has such a smooth design, that it makes working with an ECS really a pleasure (to be fair, Legion is less ergonomic than Bevy, but it's not a big deal). I'd be cautious towards Bevy; it's a product that capitalized with great success on hype; there's nothing inherently wrong with that (I don't doubt at some point it will reach a stable point), but it should be clear to users that it's currently "very alpha" (that said, I'm happy to report that Bevy made huge strides in stability/usability between v0.5 and v0.7). ¹=https://pragprog.com/titles/hwrust/hands-on-rust https://pragprog.com/titles/hwrust/hands-on-rust
