pub struct PageFaultErrorCode {
    bits: u32,
}

Describes an page fault error code.

Fields

bits: u32

Implementations

impl PageFaultErrorCode

pub const PROTECTION_VIOLATION: PageFaultErrorCode

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.

pub const CAUSED_BY_WRITE: PageFaultErrorCode

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.

pub const USER_MODE: PageFaultErrorCode

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.

pub const MALFORMED_TABLE: PageFaultErrorCode

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.

pub const INSTRUCTION_FETCH: PageFaultErrorCode

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

pub const fn empty() -> PageFaultErrorCode

Returns an empty set of flags

pub const fn all() -> PageFaultErrorCode

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<PageFaultErrorCode>

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

pub const fn from_bits_truncate(bits: u32) -> PageFaultErrorCode

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

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: PageFaultErrorCode) -> bool

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

pub const fn contains(&self, other: PageFaultErrorCode) -> bool

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

pub fn insert(&mut self, other: PageFaultErrorCode)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: PageFaultErrorCode)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: PageFaultErrorCode)

Toggles the specified flags in-place.

pub fn set(&mut self, other: PageFaultErrorCode, value: bool)

Inserts or removes the specified flags depending on the passed value.
