quote!
Use statements in
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.
