Inline modules at macro expansion time!
Initial declaration requires a path
attribute relative to the project root because on stable it is impossible to get the path of the file where the macro is invoked.
Every nested module with a path attribute will also be treated relative to the project root, although that might change in a future update.
If a path attribute is not present on a nested non-inlined module,
the macro will try to resolve it the same way the Rust compiler does - look for module_name.rs
or module_name/mod.rs
file relative to the current module.
Currently, even if you are on nighly and can use an attribute macro on a non-inlined module, you will not accomplish anything because the items get inlined after macro expansion. This macro inlines the module for you, so you can use macros on non-inlined (even nested) modules.
```rust // main.rs use inlinemod::inlinemod;
inlinemod! { #[myattr] #[path = "src/foo.rs"] mod foo; }
// foo.rs struct Bar(i32);
pub mod baz;
// foo/baz/mod.rs pub struct Hi; ```
Will get expanded to
```rust
mod foo { struct Bar(i32);
pub mod baz {
pub struct Hi;
}
} ```
All before my_attr
gets executed.
