Enum PageFaultReason 

Source 
pub enum PageFaultReason {
    NotPresent,
    ProtectionViolation,

}
Expand description

Reason a page fault occurred.

Variants§

§

NotPresent

Page is not present in the page table.

§

ProtectionViolation

A protection violation was detected (e.g., access rights mismatch).

§

WriteToReadOnly

Write to a read-only page.

§

ExecuteNoExecute

Attempt to execute a page marked as no-execute.

§

UserModeKernelAccess

User-mode code tried to access a kernel-only page.
