Methods

impl PDPTEntry

fn empty() -> PDPTEntry

Returns an empty set of flags.

fn all() -> PDPTEntry

Returns the set containing all flags.

fn bits(&self) -> u64

Returns the raw value of the flags currently stored.

fn from_bits(bits: u64) -> Option<PDPTEntry>

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

fn from_bits_truncate(bits: u64) -> PDPTEntry

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

fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

fn is_all(&self) -> bool

Returns true if all flags are currently set.

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

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

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

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

fn insert(&mut self, other: PDPTEntry)

Inserts the specified flags in-place.

fn remove(&mut self, other: PDPTEntry)

Removes the specified flags in-place.

fn toggle(&mut self, other: PDPTEntry)

Toggles the specified flags in-place.

impl PDPTEntry

fn new(pd: PhysicalAddress, flags: PDPTEntry) -> PDPTEntry

Creates a new PDPTEntry.

Arguments

• pd - The physical address of the page directory.
• flags- Additional flags for the entry.

fn get_address(self) -> PhysicalAddress

Retrieves the physical address in this entry.

fn is_present(&self) -> bool

Is page present?

fn is_writeable(&self) -> bool

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

fn is_user_mode_allowed(&self) -> bool

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

fn is_page_write_through(&self) -> bool

Page-level write-through.

fn is_page_level_cache_disabled(&self) -> bool

Page-level cache disable.

fn is_accessed(&self) -> bool

Accessed; indicates whether this entry has been used for linear-address translation.

fn is_pat(&self) -> bool

Indirectly determines the memory type used to access the 1-GByte page referenced by this entry. if not PDPT_PS this is ignored.

fn is_instruction_fetching_disabled(&self) -> bool

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