rustfmt-wrapper
Rust makes it easy to generate more Rust code--for macros, builders, whatever.
It's nice to format that code to be a little easier on the eyes. While
rustfmt
does a pretty good job, it does a pretty good job as a command and
isn't usable as a library. This is a probably-too-simple wrapper library.
It's pretty simple to use and mixes well with quote!
:
let codegen = quote!;
let formatted: String = rustfmt.unwrap;
If you need more control over the vast array of rustfmt
configuration
options, you can use the second form:
let codegen = quote!;
let config = Config ;
let narrow_formatted = rustfmt_config.unwrap;
Note that in order to use unstable configuration options, you will need to have
a the nightly version of rustfmt
installed.
Thanks to David Tolnay for so many tools including
cargo-expand
from which this
borrows.
