impl Persona
impl Persona
pub const ADDR_COMPAT_LAYOUT: Persona = Self{bits: libc::ADDR_COMPAT_LAYOUT,}
pub const ADDR_COMPAT_LAYOUT: Persona = Self{bits: libc::ADDR_COMPAT_LAYOUT,}

pub const ADDR_LIMIT_3GB: Persona = Self{bits: libc::ADDR_LIMIT_3GB,}
pub const ADDR_LIMIT_3GB: Persona = Self{bits: libc::ADDR_LIMIT_3GB,}
Use 0xc0000000
as the offset at which to search a virtual memory
chunk on mmap(2)
, otherwise use 0xffffe000
.
pub const FDPIC_FUNCPTRS: Persona = Self{bits: libc::FDPIC_FUNCPTRS,}
pub const FDPIC_FUNCPTRS: Persona = Self{bits: libc::FDPIC_FUNCPTRS,}
User-space function pointers to signal handlers point to descriptors.
pub const MMAP_PAGE_ZERO: Persona = Self{bits: libc::MMAP_PAGE_ZERO,}
pub const MMAP_PAGE_ZERO: Persona = Self{bits: libc::MMAP_PAGE_ZERO,}
Map page 0 as read-only.
pub const READ_IMPLIES_EXEC: Persona = Self{bits: libc::READ_IMPLIES_EXEC,}
pub const READ_IMPLIES_EXEC: Persona = Self{bits: libc::READ_IMPLIES_EXEC,}
PROT_READ
implies PROT_EXEC
for mmap(2)
.
pub const SHORT_INODE: Persona = Self{bits: libc::SHORT_INODE,}
pub const SHORT_INODE: Persona = Self{bits: libc::SHORT_INODE,}
No effects.
pub const STICKY_TIMEOUTS: Persona = Self{bits: libc::STICKY_TIMEOUTS,}
pub const STICKY_TIMEOUTS: Persona = Self{bits: libc::STICKY_TIMEOUTS,}
select(2)
, pselect(2)
, and ppoll(2)
do not modify the
returned timeout argument when interrupted by a signal handler.
pub const UNAME26: Persona = Self{bits: libc::UNAME26,}
pub const UNAME26: Persona = Self{bits: libc::UNAME26,}
Have uname(2)
report a 2.6.40+ version number rather than a 3.x
version number.
pub const WHOLE_SECONDS: Persona = Self{bits: libc::WHOLE_SECONDS,}
pub const WHOLE_SECONDS: Persona = Self{bits: libc::WHOLE_SECONDS,}
No effects.
pub const fn from_bits(bits: i32) -> Option<Persona>
pub const fn from_bits(bits: i32) -> Option<Persona>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub const fn from_bits_truncate(bits: i32) -> Persona
pub const fn from_bits_truncate(bits: i32) -> Persona
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub const unsafe fn from_bits_unchecked(bits: i32) -> Persona
pub const unsafe fn from_bits_unchecked(bits: i32) -> Persona
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.
pub const fn intersects(&self, other: Persona) -> bool
pub const fn intersects(&self, other: Persona) -> bool
Returns true
if there are flags common to both self
and other
.
pub const fn contains(&self, other: Persona) -> bool
pub const fn contains(&self, other: Persona) -> bool
Returns true
if all of the flags in other
are contained within self
.
pub fn set(&mut self, other: Persona, value: bool)
pub fn set(&mut self, other: Persona, value: bool)
Inserts or removes the specified flags depending on the passed value.
pub const fn intersection(self, other: Persona) -> Persona
pub const fn intersection(self, other: Persona) -> Persona
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
.
pub const fn union(self, other: Persona) -> Persona
pub const fn union(self, other: Persona) -> Persona
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
.
pub const fn difference(self, other: Persona) -> Persona
pub const fn difference(self, other: Persona) -> Persona
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
.
pub const fn symmetric_difference(self, other: Persona) -> Persona
pub const fn symmetric_difference(self, other: Persona) -> Persona
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
.
pub const fn complement(self) -> Persona
pub const fn complement(self) -> Persona
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
.
