Struct tartan_arch::x86_common::paging::Level2PageTableEntry

#[repr(transparent)]

impl Default for Level2PageTableEntry

fn default() -> Level2PageTableEntry

Returns the “default value” for a type.

impl From<Level2PageTableEntry> for usize

fn from(val: Level2PageTableEntry) -> Self

impl GenericPageTableEntry for Level2PageTableEntry

fn present(&self) -> bool

P: Indicates that this entry is mapped. Otherwise the whole entry is ignored.

fn writable(&self) -> bool

R/W: Allows writes to this memory region.

fn user(&self) -> bool

U/S: Allows access to this memory region from permission level 3. Otherwise, it is only accessible from levels 0–2.

fn write_through(&self) -> bool

PWT: Enables write-through caching for this memory region.

fn cache_disabled(&self) -> bool

PCD: Disables caching for this memory region.

fn accessed(&self) -> bool

A: Set by the processor when an instruction accesses the memory region.

fn no_execute(&self) -> bool

Available on x86-64 only.

XD/NX: Prevent the processor from executing any instructions in this memory region.

fn set_present(&mut self, value: bool)

P: Indicates that this entry is mapped. Otherwise the whole entry is ignored.

fn with_present(&mut self, value: bool) -> Self

P: Indicates that this entry is mapped. Otherwise the whole entry is ignored.

fn set_writable(&mut self, value: bool)

R/W: Allows writes to this memory region.

fn with_writable(&mut self, value: bool) -> Self

R/W: Allows writes to this memory region.

fn set_user(&mut self, value: bool)

U/S: Allows access to this memory region from permission level 3. Otherwise, it is only accessible from levels 0–2.

fn with_user(&mut self, value: bool) -> Self

U/S: Allows access to this memory region from permission level 3. Otherwise, it is only accessible from levels 0–2.

fn set_write_through(&mut self, value: bool)

PWT: Enables write-through caching for this memory region.

fn with_write_through(&mut self, value: bool) -> Self

PWT: Enables write-through caching for this memory region.

fn set_cache_disabled(&mut self, value: bool)

PCD: Disables caching for this memory region.

fn with_cache_disabled(&mut self, value: bool) -> Self

PCD: Disables caching for this memory region.

fn set_accessed(&mut self, value: bool)

A: Set by the processor when an instruction accesses the memory region.

fn with_accessed(&mut self, value: bool) -> Self

A: Set by the processor when an instruction accesses the memory region.

fn set_no_execute(&mut self, value: bool)

Available on x86-64 only.

XD/NX: Prevent the processor from executing any instructions in this memory region.

fn with_no_execute(&mut self, value: bool) -> Self

Available on x86-64 only.

XD/NX: Prevent the processor from executing any instructions in this memory region.

fn fmt_fields(&self, f: &mut DebugStruct<'_, '_>)

Print this object’s bitfield values. Helper method for Debug implementations.

impl HybridPageTableEntry for Level2PageTableEntry

fn is_page(&self) -> bool

PS: Indicates that this entry directly maps a page. Otherwise, this is a pointer to a lower-level page table.

fn set_is_page(&mut self, value: bool)

PS: Indicates that this entry directly maps a page. Otherwise, this is a pointer to a lower-level page table.

fn with_is_page(&mut self, value: bool) -> Self

PS: Indicates that this entry directly maps a page. Otherwise, this is a pointer to a lower-level page table.

fn fmt_fields(&self, f: &mut DebugStruct<'_, '_>)

Print this object’s bitfield values. Helper method for Debug implementations.

impl PartialEq<Level2PageTableEntry> for Level2PageTableEntry

fn eq(&self, other: &Level2PageTableEntry) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
