internal.rs

1//! Module containing the translation from rustc_public constructs to the rustc counterpart.
2//!
3//! This module will only include a few constructs to allow users to invoke internal rustc APIs
4//! due to incomplete stable coverage.
5
6// Prefer importing rustc_public over internal rustc constructs to make this file more readable.
