# rustfix
[](https://crates.io/crates/rustfix)
[](https://docs.rs/rustfix)
Rustfix is a library defining useful structures that represent fix suggestions from rustc.
This is a low-level library. You pass it the JSON output from `rustc`, and you can then use it to apply suggestions to in-memory strings. This library doesn't execute commands, or read or write from the filesystem.
If you are looking for the [`cargo fix`] implementation, the core of it is located in [`cargo::ops::fix`].
> This crate is maintained by the Cargo team, primarily for use by Cargo and Rust compiler test suite
> and not intended for external use (except as a transitive dependency). This
> crate may make major changes to its APIs or be deprecated without warning.
