Expand description

Why an access could not be performed.

These are values, not errors in the “the emulator broke” sense: the VM turns them into a guest-visible exit so a harness can map a fault to a signal, a fuzzing crash, or a page-fault handler, and resume if it wants to.

Variants§

ReadUnmapped

ReadPerm

ReadUninit

WriteUnmapped

WritePerm

ExecUnmapped

ExecViolation

ReadWatch

WriteWatch

AddressOverflow

The access range wrapped past the end of the address space.
