Support `use` in procmacros hygienically

Overview

Use statements in quote!

Crates.io Version Live Build Status Docs.rs Documentation

Description

Macro to simplify using Types in the quote! macro.

Usage

The quote_use! macro can be used just like quote!, but with the added functionality of adding use statements at the top:

quote_use!{
    use std::fs::read;
    
    read("src/main.rs")
}

This will expand to the equivalent statement using quote!:

quote!{
    ::std::fs::read::read("src/main.rs")
}

Prelude

This also allows to use contents of the rust prelude directly:

quote_use!{
    Some("src/main.rs")
}

Overriding prelude

When you want to use your own type instead of the prelude type this can be achieved by simply importing it like so

quote_use!{
    use anyhow::Result;
                                                                                                             
    Result
}

Different preludes

By default quote_use! uses the std prelude for 2021 edition, but this can be configured via features, and also completely disabled.

Other quote macros

There are also variants for other quote macros from syn and quote:
