pub struct PDEntry { /* fields omitted */ }Methods
impl PDEntry
fn empty() -> PDEntry
Returns an empty set of flags.
fn all() -> PDEntry
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<PDEntry>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
fn from_bits_truncate(bits: u64) -> PDEntry
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: PDEntry) -> bool
Returns true if there are flags common to both self and other.
fn contains(&self, other: PDEntry) -> bool
Returns true all of the flags in other are contained within self.
fn insert(&mut self, other: PDEntry)
Inserts the specified flags in-place.
fn remove(&mut self, other: PDEntry)
Removes the specified flags in-place.
fn toggle(&mut self, other: PDEntry)
Toggles the specified flags in-place.
impl PDEntry[src]
fn new(pt: PhysicalAddress, flags: PDEntry) -> PDEntry
Creates a new PDEntry.
Arguments
pt- The physical address of the page table.flags- Additional flags for the entry.
fn get_address(self) -> PhysicalAddress
Retrieves the physical address in this entry.
fn is_present(&self) -> bool
Present; must be 1 to map a 2-MByte page or reference a page table.
fn is_writeable(&self) -> bool
Read/write; if 0, writes may not be allowed to the 2-MByte region controlled by this entry
fn is_user_mode_allowed(&self) -> bool
User/supervisor; user-mode accesses are not allowed to the 2-MByte 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; if PD_PS set indicates whether software has accessed the 2-MByte page else indicates whether this entry has been used for linear-address translation.
fn is_dirty(&self) -> bool
Dirty; if PD_PS set indicates whether software has written to the 2-MByte page referenced by this entry else ignored.
fn is_page(&self) -> bool
Page size; if set this entry maps a 2-MByte page; otherwise, this entry references a page directory.
fn is_global(&self) -> bool
Global; if PD_PS && CR4.PGE = 1, determines whether the translation is global; ignored otherwise if not PD_PS this is ignored.
fn is_pat(&self) -> bool
Indirectly determines the memory type used to access the 2-MByte page referenced by this entry. if not PD_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 2-Mbyte region.
