change `#[salsa::query_group]` attribute to take a struct name 2019-01-25 15:25:17 +00:00			`#[salsa::query_group(MyStruct)]`
make query_group macro procedural Switch to a procedural implementation of the `query_group!` macro, residing in the `components/salsa_macros` subcrate. Allow the user to override the invoked function via `salsa::invoke(...)` and the name of the generated query type via `salsa::query_type(...)`. In all tests, replace the `salsa::query_group! { ... }` invocations with the new attribute-style `#[salsa::query_group]` macro, and change them to the new naming scheme for query types (`...Query`). Update README, examples, and documentation. 2019-01-12 10:11:59 +00:00			`trait MyDatabase: salsa::Database {`
