[][src]Struct x86_64::structures::paging::page_table::PageTableEntry

#[repr(transparent)]pub struct PageTableEntry { /* fields omitted */ }

A 64-bit page table entry.

Methods

impl PageTableEntry[src]

pub const fn new() -> Self[src]

Creates an unused page table entry.

pub const 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 const 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 the PRESENT flag set.
  • FrameError::HugeFrame if the entry has the HUGE_PAGE flag set (for huge pages the addr 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.
