Implementations
sourceimpl PageFaultErrorCode
impl PageFaultErrorCode
sourcepub const PROTECTION_VIOLATION: Self
pub const PROTECTION_VIOLATION: 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.
sourcepub const CAUSED_BY_WRITE: Self
pub const CAUSED_BY_WRITE: 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.
sourcepub const USER_MODE: Self
pub const USER_MODE: 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.
sourcepub const MALFORMED_TABLE: Self
pub const MALFORMED_TABLE: 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.
sourcepub const INSTRUCTION_FETCH: Self
pub const INSTRUCTION_FETCH: Self
If this flag is set, it indicates that the access that caused the page fault was an instruction fetch.
sourcepub const PROTECTION_KEY: Self
pub const PROTECTION_KEY: Self
If this flag is set, it indicates that the page fault was caused by a protection key.
sourcepub const SHADOW_STACK: Self
pub const SHADOW_STACK: Self
If this flag is set, it indicates that the page fault was caused by a shadow stack access.
sourcepub const SGX: Self
pub const SGX: Self
If this flag is set, it indicates that the page fault was caused by SGX access-control requirements (Intel-only).
sourcepub const RMP: Self
pub const RMP: Self
If this flag is set, it indicates that the page fault is a result of the processor encountering an RMP violation (AMD-only).
sourcepub const fn from_bits(bits: u64) -> Option<Self>
pub const fn from_bits(bits: u64) -> Option<Self>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
sourcepub const fn from_bits_truncate(bits: u64) -> Self
pub const fn from_bits_truncate(bits: u64) -> Self
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
sourcepub const unsafe fn from_bits_unchecked(bits: u64) -> Self
pub const unsafe fn from_bits_unchecked(bits: u64) -> Self
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
Safety
The caller of the bitflags!
macro can chose to allow or
disallow extra bits for their bitflags type.
The caller of from_bits_unchecked()
has to ensure that
all bits correspond to a defined flag or that extra bits
are valid for this bitflags type.
sourcepub const fn intersects(&self, other: Self) -> bool
pub const fn intersects(&self, other: Self) -> bool
Returns true
if there are flags common to both self
and other
.
sourcepub const fn contains(&self, other: Self) -> bool
pub const fn contains(&self, other: Self) -> bool
Returns true
if all of the flags in other
are contained within self
.
sourcepub fn set(&mut self, other: Self, value: bool)
pub fn set(&mut self, other: Self, value: bool)
Inserts or removes the specified flags depending on the passed value.
sourcepub const fn intersection(self, other: Self) -> Self
pub const fn intersection(self, other: Self) -> Self
Returns the intersection between the flags in self
and
other
.
Specifically, the returned set contains only the flags which are
present in both self
and other
.
This is equivalent to using the &
operator (e.g.
ops::BitAnd
), as in flags & other
.
sourcepub const fn union(self, other: Self) -> Self
pub const fn union(self, other: Self) -> Self
Returns the union of between the flags in self
and other
.
Specifically, the returned set contains all flags which are
present in either self
or other
, including any which are
present in both (see Self::symmetric_difference
if that
is undesirable).
This is equivalent to using the |
operator (e.g.
ops::BitOr
), as in flags | other
.
sourcepub const fn difference(self, other: Self) -> Self
pub const fn difference(self, other: Self) -> Self
Returns the difference between the flags in self
and other
.
Specifically, the returned set contains all flags present in
self
, except for the ones present in other
.
It is also conceptually equivalent to the “bit-clear” operation:
flags & !other
(and this syntax is also supported).
This is equivalent to using the -
operator (e.g.
ops::Sub
), as in flags - other
.
sourcepub const fn symmetric_difference(self, other: Self) -> Self
pub const fn symmetric_difference(self, other: Self) -> Self
Returns the symmetric difference between the flags
in self
and other
.
Specifically, the returned set contains the flags present which
are present in self
or other
, but that are not present in
both. Equivalently, it contains the flags present in exactly
one of the sets self
and other
.
This is equivalent to using the ^
operator (e.g.
ops::BitXor
), as in flags ^ other
.
sourcepub const fn complement(self) -> Self
pub const fn complement(self) -> Self
Returns the complement of this set of flags.
Specifically, the returned set contains all the flags which are
not set in self
, but which are allowed for this type.
Alternatively, it can be thought of as the set difference
between Self::all()
and self
(e.g. Self::all() - self
)
This is equivalent to using the !
operator (e.g.
ops::Not
), as in !flags
.
