}Methods
impl PDPTEntry[src]
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[src]
fn new(pd: PAddr, 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) -> PAddr[−]
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.
