[−][src]Struct x86_64::structures::paging::page_table::PageTableEntry
A 64-bit page table entry.
Methods
impl PageTableEntry
[src]
pub fn new() -> Self
[src]
Creates an unused page table entry.
pub fn is_unused(&self) -> bool
[src]
Returns whether this entry is zero.
pub fn set_unused(&mut self)
[src]
Sets this entry to zero.
pub fn flags(&self) -> PageTableFlags
[src]
Returns the flags of this entry.
pub fn addr(&self) -> PhysAddr
[src]
Returns the physical address mapped by this entry, might be zero.
pub fn frame(&self) -> Result<PhysFrame, FrameError>
[src]
Returns the physical frame mapped by this entry.
Returns the following errors:
FrameError::FrameNotPresent
if the entry doesn't have thePRESENT
flag set.FrameError::HugeFrame
if the entry has theHUGE_PAGE
flag set (for huge pages theaddr
function must be used)
pub fn set_addr(&mut self, addr: PhysAddr, flags: PageTableFlags)
[src]
Map the entry to the specified physical address with the specified flags.
pub fn set_frame(&mut self, frame: PhysFrame, flags: PageTableFlags)
[src]
Map the entry to the specified physical frame with the specified flags.
pub fn set_flags(&mut self, flags: PageTableFlags)
[src]
Sets the flags of this entry.
