pub struct InterpErrorInfo<'tcx>(Box<InterpErrorInfoInner<'tcx>>);
Expand description

Packages the kind of error we got from the const code interpreter up with a Rust-level backtrace of where the error occurred. These should always be constructed by calling .into() on an InterpError. In rustc_mir::interpret, we have throw_err_* macros for this.
