Expand description

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(ErrorGuaranteed)

Abort in case errors are already reported.

Layout(LayoutError<'tcx>)

An error occurred during layout computation.

FnAbiAdjustForForeignAbi(AdjustForForeignAbiError)

An error occurred during FnAbi computation: the passed –target lacks FFI support (which unfortunately typeck does not reject). Not using FnAbiError as that contains a nested LayoutError.

SizeOfUnsizedType(Ty<'tcx>)

SizeOf of unsized type was requested.

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.
