i made a new crate with cargo init, created this Cargo.toml
[package]
name = "hecs-test"
version = "0.1.0"
edition = "2021"
[dependencies]
hecs = { version = "0.10.0", features = ["macros"] }
and made this src/main.rs
use hecs::*;
#[derive(Query)]
struct Test<'a>;
fn main() {}
i get many errors:

Some errors have detailed explanations: E0107, E0220, E0407, E0437.
For more information about an error, try `rustc --explain E0107`.
i can't think of any more information i would be able to give, the macro backtrace isn't helpful, it just points to the macro's function signature.
Looks like we forgot to bump hecs-macros following some recent breakage, and tests didn't catch this because they all use a path dep. Fixed in 0.10.1. Thanks for the report!
