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!
