Implementations

impl PTFlags

pub const P: PTFlags

Present; must be 1 to map a 4-KByte page.

pub const RW: PTFlags

Read/write; if 0, writes may not be allowed to the 4-KByte region controlled by this entry

User/supervisor; user-mode accesses are not allowed to the 4-KByte region controlled by this entry.

pub const PWT: PTFlags

Page-level write-through.

pub const PCD: PTFlags

Page-level cache disable.

pub const A: PTFlags

Accessed; indicates whether software has accessed the 4-KByte page

pub const D: PTFlags

Dirty; indicates whether software has written to the 4-KByte page referenced by this entry.

pub const G: PTFlags

Global; if CR4.PGE = 1, determines whether the translation is global (see Section 4.10); ignored otherwise

pub const XD: PTFlags

If IA32_EFER.NXE = 1, execute-disable If 1, instruction fetches are not allowed from the 512-GByte region.

pub const fn empty() -> PTFlags

Returns an empty set of flags

pub const fn all() -> PTFlags

Returns the set containing all flags.

pub const fn bits(&self) -> u64

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u64) -> Option<PTFlags>

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

pub const fn from_bits_truncate(bits: u64) -> PTFlags

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

pub const unsafe fn from_bits_unchecked(bits: u64) -> PTFlags

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

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: PTFlags) -> bool

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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