impl Cr3Flags
sourcepub const PAGE_LEVEL_WRITETHROUGH: Self = _
 
pub const PAGE_LEVEL_WRITETHROUGH: Self = _

impl Cr3Flags
sourcepub const fn bits(&self) -> u64
 
pub const fn bits(&self) -> u64
Get the underlying bits value.
The returned value is exactly the bits set in this flags value.
sourcepub const fn from_bits(bits: u64) -> Option<Self>
 
pub const fn from_bits(bits: u64) -> Option<Self>
Convert from a bits value.
This method will return None if any unknown bits are set.
sourcepub const fn from_bits_truncate(bits: u64) -> Self
 
pub const fn from_bits_truncate(bits: u64) -> Self
Convert from a bits value, unsetting any unknown bits.
sourcepub const fn from_bits_retain(bits: u64) -> Self
 
pub const fn from_bits_retain(bits: u64) -> Self
Convert from a bits value exactly.
sourcepub fn from_name(name: &str) -> Option<Self>
 
pub fn from_name(name: &str) -> Option<Self>
Get a flags value with the bits of a flag with the given name set.
This method will return None if name is empty or doesn’t
correspond to any named flag.
sourcepub const fn intersects(&self, other: Self) -> bool
 
pub const fn intersects(&self, other: Self) -> bool
Whether any set bits in a source flags value are also set in a target flags value.
sourcepub const fn contains(&self, other: Self) -> bool
 
pub const fn contains(&self, other: Self) -> bool
Whether all set bits in a source flags value are also set in a target flags value.
sourcepub fn remove(&mut self, other: Self)
 
pub fn remove(&mut self, other: Self)
The intersection of a source flags value with the complement of a target flags value (&!).
This method is not equivalent to self & !other when other has unknown bits set.
remove won’t truncate other, but the ! operator will.
sourcepub fn toggle(&mut self, other: Self)
 
pub fn toggle(&mut self, other: Self)
The bitwise exclusive-or (^) of the bits in two flags values.
sourcepub fn set(&mut self, other: Self, value: bool)
 
pub fn set(&mut self, other: Self, value: bool)
Call insert when value is true or remove when value is false.
sourcepub const fn intersection(self, other: Self) -> Self
 
pub const fn intersection(self, other: Self) -> Self
The bitwise and (&) of the bits in two flags values.
sourcepub const fn union(self, other: Self) -> Self
 
pub const fn union(self, other: Self) -> Self
The bitwise or (|) of the bits in two flags values.
sourcepub const fn difference(self, other: Self) -> Self
 
pub const fn difference(self, other: Self) -> Self
The intersection of a source flags value with the complement of a target flags value (&!).
This method is not equivalent to self & !other when other has unknown bits set.
difference won’t truncate other, but the ! operator will.
sourcepub const fn symmetric_difference(self, other: Self) -> Self
 
pub const fn symmetric_difference(self, other: Self) -> Self
The bitwise exclusive-or (^) of the bits in two flags values.
sourcepub const fn complement(self) -> Self
 
pub const fn complement(self) -> Self
The bitwise negation (!) of the bits in a flags value, truncating the result.
source§impl Cr3Flags
 
impl Cr3Flags
sourcepub const fn iter(&self) -> Iter<Cr3Flags>
 
pub const fn iter(&self) -> Iter<Cr3Flags>
Yield a set of contained flags values.
Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.
sourcepub const fn iter_names(&self) -> IterNames<Cr3Flags>
 
pub const fn iter_names(&self) -> IterNames<Cr3Flags>
Yield a set of contained named flags values.
This method is like iter, except only yields bits in contained named flags.
Any unknown bits, or bits not corresponding to a contained flag will not be yielded.

impl Cr3Flags
sourcepub const unsafe fn from_bits_unchecked(bits: u64) -> Self
 👎Deprecated: use the safe from_bits_retain method instead
pub const unsafe fn from_bits_unchecked(bits: u64) -> Self
from_bits_retain method insteadConvert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
