Enum VmExit 

pub enum VmExit {
    InstructionLimit,
    Breakpoint(u64),
    Fault(MemFault),
    Unlifted {
        addr: u64,
        error: CodeError,
    },
    Interrupt(Interrupt),
    HookStop(HookId),
    Error(Box<str>),
}

Why the machine stopped.

Variants

InstructionLimit

The step budget ran out. The machine is resumable.

Breakpoint(u64)

Execution reached an address with a breakpoint on it. The breakpoint instruction has not been executed.

Fault(MemFault)

A memory access failed.

Unlifted

Code at this address could not be lifted.

Fields

addr: u64

error: CodeError

Interrupt(Interrupt)

The machine stopped at a user p-code operation for the host to act: an explicit vm.interrupt, or an op the interpreter has no semantics for (syscall, cpuid, rdtsc, …). Everything before the op in its block has retired and nothing after it has run. The machine stays there until Vm::resume supplies the op’s effect; running again without resuming reports the same interrupt.

HookStop(HookId)

A hook registered through the table asked the run to stop. For a code or memory hook the machine is before the hooked guest instruction, and running again executes it without notifying the hook again. For an instruction hook the user op is still pending, as Interrupt describes, until the caller resumes it.

Error(Box<str>)

The interpreter reported something the VM does not model as a guest event — a malformed block, an internal failure.
