Macro quote_alias::alias

macro_rules! alias {
    ($( $(#[doc = $doc:expr])* $vis:vis $ident:ident $body:tt ),* $(,)?) => { ... };
    (@struct $vis:vis $ident:ident { $($tt:tt)* }) => { ... };
    (@struct $vis:vis $ident:ident ( $($tt:tt)* )) => { ... };
}

Assigns a token stream to an identifier.

This is done by generating a unit struct that implements ToTokens. The struct can be then interpolated in quote! invocations or have its ToTokens methods called directly.

Visibility and doc comments are also passed through to the struct.

Usage

use quote_alias::alias;
use quote::quote;

alias! {
    /// `Foo` from `my_crate::foo`
    pub Foo(my_crate::foo::Foo),
     
    this_and_that {
        my_crate::this();
        my_crate::that();
    },
}

// same as: quote! { my_crate::foo::Foo::new() };
quote! { #Foo::new() };

// same as: quote! {
//     my_crate::this();
//     my_crate::that();
// };
quote! { #this_and_that };
