Enum rustc_middle::mir::interpret::InvalidProgramInfo

pub enum InvalidProgramInfo<'tcx> {
    TooGeneric,
    ReferencedConstant,
    AlreadyReported(ErrorReported),
    Layout(LayoutError<'tcx>),
    TransmuteSizeDiff(Ty<'tcx>, Ty<'tcx>),
    SizeOfUnsizedType(Ty<'tcx>),
}

Error information for when the program we executed turned out not to actually be a valid program. This cannot happen in stand-alone Miri, but it can happen during CTFE/ConstProp where we work on generic code or execution does not have all information available.

Variants

TooGeneric

Resolution can fail if we are in a too generic context.

ReferencedConstant

Cannot compute this constant because it depends on another one which already produced an error.

AlreadyReported(ErrorReported)

Abort in case errors are already reported.

Tuple Fields of AlreadyReported

0: ErrorReported

Layout(LayoutError<'tcx>)

An error occurred during layout computation.

Tuple Fields of Layout

0: LayoutError<'tcx>

TransmuteSizeDiff(Ty<'tcx>, Ty<'tcx>)

An invalid transmute happened.

Tuple Fields of TransmuteSizeDiff

0: Ty<'tcx>1: Ty<'tcx>

SizeOfUnsizedType(Ty<'tcx>)

SizeOf of unsized type was requested.

Tuple Fields of SizeOfUnsizedType

0: Ty<'tcx>

Trait Implementations

impl Display for InvalidProgramInfo<'_>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
