Available on x86 or x86-64 only.

An page table entry (any level) that directly maps a page.

Provided Methods

fn dirty(&self) -> bool

D: Set by the processor when an instruction modifies the memory region.

fn attribute_table(&self) -> bool

PAT: Used to associate this page with a page attribute table.

In 32-bit mode, requires BasicFeatures::page_attribute_table. Always applicable in 64-bit mode.

fn global(&self) -> bool

G: Indicates that this is a global page shared by all task contexts.

Requires ControlRegister4::global_pages.

fn protection_key(&self) -> u8

Available on x86-64 only.

The protection key that applies to this memory region.

Requires ControlRegister4::user_protection_keys or ControlRegister4::supervisor_protection_keys.

fn set_dirty(&mut self, value: bool)

D: Set by the processor when an instruction modifies the memory region.

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

D: Set by the processor when an instruction modifies the memory region.

fn set_attribute_table(&mut self, value: bool)

PAT: Used to associate this page with a page attribute table.

In 32-bit mode, requires BasicFeatures::page_attribute_table. Always applicable in 64-bit mode.

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

PAT: Used to associate this page with a page attribute table.

In 32-bit mode, requires BasicFeatures::page_attribute_table. Always applicable in 64-bit mode.

fn set_global(&mut self, value: bool)

G: Indicates that this is a global page shared by all task contexts.

Requires ControlRegister4::global_pages.

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

G: Indicates that this is a global page shared by all task contexts.

Requires ControlRegister4::global_pages.

fn set_protection_key(&mut self, value: u8)

Available on x86-64 only.

The protection key that applies to this memory region.

Requires ControlRegister4::user_protection_keys or ControlRegister4::supervisor_protection_keys.

fn with_protection_key(&self, value: u8) -> Self

Available on x86-64 only.

The protection key that applies to this memory region.

Requires ControlRegister4::user_protection_keys or ControlRegister4::supervisor_protection_keys.

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

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