Struct x86_64::structures::idt::PageFaultErrorCode [] [src]

pub struct PageFaultErrorCode { /* fields omitted */ }

Describes an page fault error code.

Methods

impl PageFaultErrorCode
[src]

PROTECTION_VIOLATION: PageFaultErrorCodeAngleBracketed { lifetimes: [], types: [], bindings: [] } = PageFaultErrorCode{bits: 1 << 0,}

If this flag is set, the page fault was caused by a page-protection violation, else the page fault was caused by a not-present page.

CAUSED_BY_WRITE: PageFaultErrorCodeAngleBracketed { lifetimes: [], types: [], bindings: [] } = PageFaultErrorCode{bits: 1 << 1,}

If this flag is set, the memory access that caused the page fault was a write. Else the access that caused the page fault is a memory read. This bit does not necessarily indicate the cause of the page fault was a read or write violation.

USER_MODE: PageFaultErrorCodeAngleBracketed { lifetimes: [], types: [], bindings: [] } = PageFaultErrorCode{bits: 1 << 2,}

If this flag is set, an access in user mode (CPL=3) caused the page fault. Else an access in supervisor mode (CPL=0, 1, or 2) caused the page fault. This bit does not necessarily indicate the cause of the page fault was a privilege violation.

MALFORMED_TABLE: PageFaultErrorCodeAngleBracketed { lifetimes: [], types: [], bindings: [] } = PageFaultErrorCode{bits: 1 << 3,}

If this flag is set, the page fault is a result of the processor reading a 1 from a reserved field within a page-translation-table entry.

INSTRUCTION_FETCH: PageFaultErrorCodeAngleBracketed { lifetimes: [], types: [], bindings: [] } = PageFaultErrorCode{bits: 1 << 4,}

If this flag is set, it indicates that the access that caused the page fault was an instruction fetch.

Returns an empty set of flags.

Returns the set containing all flags.

Returns the raw value of the flags currently stored.

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

Returns true if no flags are currently stored.

Returns true if all flags are currently set.

Returns true if there are flags common to both self and other.

Returns true all of the flags in other are contained within self.

Inserts the specified flags in-place.

Removes the specified flags in-place.

Toggles the specified flags in-place.
