Variants

UndefinedBehavior(UndefinedBehaviorInfo)

The program caused undefined behavior.

Unsupported(UnsupportedOpInfo)

The program did something the interpreter does not support (some of these might be UB but the interpreter is not sure).

InvalidProgram(InvalidProgramInfo<'tcx>)

The program was invalid (ill-typed, bad MIR, not sufficiently monomorphized, …).

ResourceExhaustion(ResourceExhaustionInfo)

The program exhausted the interpreter’s resources (stack/heap too big, execution takes too long, …).

MachineStop(Box<dyn MachineStopType + 'static, Global>)

Stop execution for a machine-controlled reason. This is never raised by the core engine itself.

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.
