rustc_middle::mir::interpret::error

Struct InterpErrorInfo

Source 
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.

Interpreter errors must not be silently discarded (that will lead to a panic). Instead, explicitly call discard_err if this is really the right thing to do. Note that if this happens during const-eval or in Miri, it could lead to a UB error being lost!
