Module rustc_const_eval::transform::check_consts

Check the bodies of consts, statics and const fns for illegal operations.

This module will eventually replace the parts of qualify_consts.rs that check whether a local has interior mutability or needs to be dropped, as well as the visitor that emits errors when it finds operations that are invalid in a certain context.

Re-exports

pub use self::qualifs::Qualif;
