@ -6,7 +6,7 @@ The [`rustc_driver`] is essentially `rustc`'s `main` function.
It acts as the glue for running the various phases of the compiler in the correct order,
using the interface defined in the [`rustc_interface`] crate. Where possible, using [`rustc_driver`] rather than [`rustc_interface`] is recommended.
The main entry point of [`rustc_driver`] is [`rustc_driver::RunCompiler`][rd_rc].
The main entry point of [`rustc_driver`] is [`rustc_driver::run_compiler`][rd_rc].
This builder accepts the same command-line args as rustc as well as an implementation of [`Callbacks`][cb] and a couple of other optional options.
[`Callbacks`][cb] is a `trait` that allows for custom compiler configuration,
as well as allowing custom code to run after different phases of the compilation.
