pub struct Cr0Flags { /* fields omitted */ }
Configuration flags of the Cr0 register.
Methods
impl Cr0Flags
impl Cr0Flags
pub const PROTECTED_MODE_ENABLE: Cr0Flags
PROTECTED_MODE_ENABLE: Cr0Flags = Cr0Flags{bits: 1 << 0,}
Enables protected mode.
pub const MONITOR_COPROCESSOR: Cr0Flags
MONITOR_COPROCESSOR: Cr0Flags = Cr0Flags{bits: 1 << 1,}
Enables monitoring of the coprocessor, typical for x87 instructions.
Controls together with the TASK_SWITCHED
flag whether a wait
or fwait
instruction should cause a device-not-available exception.
pub const EMULATE_COPROCESSOR: Cr0Flags
EMULATE_COPROCESSOR: Cr0Flags = Cr0Flags{bits: 1 << 2,}
Force all x87 and MMX instructions to cause an exception.
pub const TASK_SWITCHED: Cr0Flags
TASK_SWITCHED: Cr0Flags = Cr0Flags{bits: 1 << 3,}
Automatically set to 1 on hardware task switch.
This flags allows lazily saving x87/MMX/SSE instructions on hardware context switches.
pub const NUMERIC_ERROR: Cr0Flags
NUMERIC_ERROR: Cr0Flags = Cr0Flags{bits: 1 << 5,}
Enables the native error reporting mechanism for x87 FPU errors.
pub const WRITE_PROTECT: Cr0Flags
WRITE_PROTECT: Cr0Flags = Cr0Flags{bits: 1 << 16,}
Controls whether supervisor-level writes to read-only pages are inhibited.
When set, it is not possible to write to read-only pages from ring 0.
pub const ALIGNMENT_MASK: Cr0Flags
ALIGNMENT_MASK: Cr0Flags = Cr0Flags{bits: 1 << 18,}
Enables automatic alignment checking.
pub const NOT_WRITE_THROUGH: Cr0Flags
NOT_WRITE_THROUGH: Cr0Flags = Cr0Flags{bits: 1 << 29,}
Ignored. Used to control write-back/write-through cache strategy on older CPUs.
pub const CACHE_DISABLE: Cr0Flags
CACHE_DISABLE: Cr0Flags = Cr0Flags{bits: 1 << 30,}
Disables internal caches (only for some cases).
pub const PAGING: Cr0Flags
PAGING: Cr0Flags = Cr0Flags{bits: 1 << 31,}
Enables page translation.
pub fn empty() -> Cr0Flags
pub fn empty() -> Cr0Flags

pub fn all() -> Cr0Flags
pub fn all() -> Cr0Flags
Returns the set containing all flags.
pub fn bits(&self) -> u64
pub fn bits(&self) -> u64
Returns the raw value of the flags currently stored.
pub fn from_bits(bits: u64) -> Option<Cr0Flags>
pub fn from_bits(bits: u64) -> Option<Cr0Flags>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub fn from_bits_truncate(bits: u64) -> Cr0Flags
pub fn from_bits_truncate(bits: u64) -> Cr0Flags
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub fn is_empty(&self) -> bool
pub fn is_empty(&self) -> bool
Returns true
if no flags are currently stored.
pub fn is_all(&self) -> bool
pub fn is_all(&self) -> bool
Returns true
if all flags are currently set.
pub fn intersects(&self, other: Cr0Flags) -> bool
pub fn intersects(&self, other: Cr0Flags) -> bool
Returns true
if there are flags common to both self
and other
.
pub fn contains(&self, other: Cr0Flags) -> bool
pub fn contains(&self, other: Cr0Flags) -> bool
Returns true
all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: Cr0Flags)
pub fn insert(&mut self, other: Cr0Flags)
Inserts the specified flags in-place.
pub fn remove(&mut self, other: Cr0Flags)
pub fn remove(&mut self, other: Cr0Flags)
Removes the specified flags in-place.
pub fn toggle(&mut self, other: Cr0Flags)
pub fn toggle(&mut self, other: Cr0Flags)
Toggles the specified flags in-place.
pub fn set(&mut self, other: Cr0Flags, value: bool)
pub fn set(&mut self, other: Cr0Flags, value: bool)
Inserts or removes the specified flags depending on the passed value.
