Bits: 0..1

pub const fn with_protection_checked(self, value: bool) -> Result<Self, ()>

If this flag is set, the page fault was caused by a page-protection violation, else the page fault was caused by a not-present page.

Bits: 0..1

pub const fn with_protection(self, value: bool) -> Self

Bits: 0..1

pub fn set_protection_checked(&mut self, value: bool) -> Result<(), ()>

If this flag is set, the page fault was caused by a page-protection violation, else the page fault was caused by a not-present page.

Bits: 0..1

pub const fn write(&self) -> bool

If this flag is set, the memory access that caused the page fault was a write. Else the access that caused the page fault is a memory read. This bit does not necessarily indicate the cause of the page fault was a read or write violation.

Bits: 1..2

pub const fn with_write_checked(self, value: bool) -> Result<Self, ()>

If this flag is set, the memory access that caused the page fault was a write. Else the access that caused the page fault is a memory read. This bit does not necessarily indicate the cause of the page fault was a read or write violation.

Bits: 1..2

pub const fn with_write(self, value: bool) -> Self

If this flag is set, the memory access that caused the page fault was a write. Else the access that caused the page fault is a memory read. This bit does not necessarily indicate the cause of the page fault was a read or write violation.

Bits: 1..2

pub fn set_write(&mut self, value: bool)

If this flag is set, the memory access that caused the page fault was a write. Else the access that caused the page fault is a memory read. This bit does not necessarily indicate the cause of the page fault was a read or write violation.

Bits: 1..2

pub fn set_write_checked(&mut self, value: bool) -> Result<(), ()>

If this flag is set, the memory access that caused the page fault was a write. Else the access that caused the page fault is a memory read. This bit does not necessarily indicate the cause of the page fault was a read or write violation.

Bits: 1..2

pub const fn user(&self) -> bool

If this flag is set, an access in user mode (CPL=3) caused the page fault. Else an access in supervisor mode (CPL=0, 1, or 2) caused the page fault. This bit does not necessarily indicate the cause of the page fault was a privilege violation.

Bits: 2..3

pub const fn with_user_checked(self, value: bool) -> Result<Self, ()>

If this flag is set, an access in user mode (CPL=3) caused the page fault. Else an access in supervisor mode (CPL=0, 1, or 2) caused the page fault. This bit does not necessarily indicate the cause of the page fault was a privilege violation.

Bits: 2..3

pub const fn with_user(self, value: bool) -> Self

If this flag is set, an access in user mode (CPL=3) caused the page fault. Else an access in supervisor mode (CPL=0, 1, or 2) caused the page fault. This bit does not necessarily indicate the cause of the page fault was a privilege violation.

Bits: 2..3

pub fn set_user(&mut self, value: bool)

If this flag is set, an access in user mode (CPL=3) caused the page fault. Else an access in supervisor mode (CPL=0, 1, or 2) caused the page fault. This bit does not necessarily indicate the cause of the page fault was a privilege violation.

Bits: 2..3

pub fn set_user_checked(&mut self, value: bool) -> Result<(), ()>

If this flag is set, an access in user mode (CPL=3) caused the page fault. Else an access in supervisor mode (CPL=0, 1, or 2) caused the page fault. This bit does not necessarily indicate the cause of the page fault was a privilege violation.

Bits: 2..3

pub const fn table(&self) -> bool

If this flag is set, the page fault is a result of the processor reading a 1 from a reserved field within a page-translation-table entry.

Bits: 3..4

pub const fn with_table_checked(self, value: bool) -> Result<Self, ()>

If this flag is set, the page fault is a result of the processor reading a 1 from a reserved field within a page-translation-table entry.

Bits: 3..4

pub const fn with_table(self, value: bool) -> Self

If this flag is set, the page fault is a result of the processor reading a 1 from a reserved field within a page-translation-table entry.
