Macros

Macros are basically code that generates other code.

There are mainly 2 kinds of macros in rust:

- Declarative macros

- Procedural macros/Proc Macros

Jonhoo did a nice beginner friendly video on declarative macros on his channel

Interesting macro patterns

- Seen in [smol](https://crates.io/crates/smol)

#[macro_export]
macro_rules! my_macro {
    ($($expr:tt)*) => {
        $crate::MyStruct::myfunc(async move { $($expr)* }).await
    };
}
