Use statements in quote!

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:

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

This will expand to the equivalent statement using [quote!]:

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

Prelude

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

## use quote_use::quote_use;
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

## use quote_use::quote_use;
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.

• prelude_std: Enables [std::prelude::v1] (incompatible with prelude_core)
• prelude_core: Enables [core::prelude::v1] (incompatible with prelude_std)
• prelude_2021: Enables [core::prelude::rust_2021] (requires either prelude_std or prelude_core)
