[−]Struct x86_64::structures::paging::PageTableFlags
Possible flags for a page table entry.
Methods
impl PageTableFlags
impl PageTableFlags
pub const PRESENT: PageTableFlags
Specifies whether the mapped frame or page table is loaded in memory.
pub const WRITABLE: PageTableFlags
Controls whether writes to the mapped frames are allowed.
If this bit is unset in a level 1 page table entry, the mapped frame is read-only. If this bit is unset in a higher level page table entry the complete range of mapped pages is read-only.
pub const USER_ACCESSIBLE: PageTableFlags
Controls whether accesses from userspace (i.e. ring 3) are permitted.
pub const WRITE_THROUGH: PageTableFlags
If this bit is set, a “write-through” policy is used for the cache, else a “write-back” policy is used.
pub const NO_CACHE: PageTableFlags
Disables caching for the pointed entry is cacheable.
pub const ACCESSED: PageTableFlags
Set by the CPU when the mapped frame or page table is accessed.
pub const DIRTY: PageTableFlags
Set by the CPU on a write to the mapped frame.
pub const HUGE_PAGE: PageTableFlags
Specifies that the entry maps a huge frame instead of a page table. Only allowed in P2 or P3 tables.
pub const GLOBAL: PageTableFlags
Indicates that the mapping is present in all address spaces, so it isn't flushed from the TLB on an address space switch.

pub const BIT_60: PageTableFlags
Available to the OS, can be used to store additional data, e.g. custom flags.
pub const BIT_61: PageTableFlags
Available to the OS, can be used to store additional data, e.g. custom flags.
pub const BIT_62: PageTableFlags
Available to the OS, can be used to store additional data, e.g. custom flags.
pub const NO_EXECUTE: PageTableFlags
Forbid code execution from the mapped frames.
Can be only used when the no-execute page protection feature is enabled in the EFER register.
pub fn empty() -> PageTableFlags |
Returns an empty set of flags.
pub fn all() -> PageTableFlags |
Returns the set containing all flags.
pub fn bits(&self) -> u64 |
Returns the raw value of the flags currently stored.
pub fn from_bits(bits: u64) -> Option<PageTableFlags> |
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub fn from_bits_truncate(bits: u64) -> PageTableFlags |
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub fn is_empty(&self) -> bool |
Returns true
if no flags are currently stored.
pub fn is_all(&self) -> bool |
Returns true
if all flags are currently set.
pub fn intersects(&self, other: PageTableFlags) -> bool |
Returns true
if there are flags common to both self
and other
.
pub fn contains(&self, other: PageTableFlags) -> bool |
Returns true
all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: PageTableFlags) |
Inserts the specified flags in-place.
pub fn remove(&mut self, other: PageTableFlags) |
Removes the specified flags in-place.
pub fn toggle(&mut self, other: PageTableFlags) |
Toggles the specified flags in-place.
pub fn set(&mut self, other: PageTableFlags, value: bool) |
Inserts or removes the specified flags depending on the passed value.
