Methods

impl PDPTFlags

pub const P: PDPTFlags

Present; must be 1 to map a 1-GByte page or reference a page directory.

pub const RW: PDPTFlags

Read/write; if 0, writes may not be allowed to the 1-GByte region controlled by this entry

pub const US: PDPTFlags

User/supervisor; user-mode accesses are not allowed to the 1-GByte region controlled by this entry.

pub const PWT: PDPTFlags

Page-level write-through.

pub const PCD: PDPTFlags

Page-level cache disable.

pub const A: PDPTFlags

Accessed; if PS set indicates whether software has accessed the 1-GByte page else indicates whether this entry has been used for linear-address translation

pub const D: PDPTFlags

Dirty; if PS indicates whether software has written to the 1-GByte page referenced by this entry. else ignored.

pub const PS: PDPTFlags

Page size; if set this entry maps a 1-GByte page; otherwise, this entry references a page directory. if not PS this is ignored.

pub const G: PDPTFlags

Global; if PS && CR4.PGE = 1, determines whether the translation is global; ignored otherwise if not PS this is ignored.

pub const PAT: PDPTFlags

Indirectly determines the memory type used to access the 1-GByte page referenced by this entry.

pub const XD: PDPTFlags

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

pub fn empty() -> PDPTFlags

Returns an empty set of flags.

pub fn all() -> PDPTFlags

Returns the set containing all flags.

pub fn bits(&self) -> u64

Returns the raw value of the flags currently stored.

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

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

pub fn from_bits_truncate(bits: u64) -> PDPTFlags

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

pub fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub fn is_all(&self) -> bool

Returns true if all flags are currently set.

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

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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