Implementations

impl OFlags

pub const ACCMODE: OFlags = Self{ bits: linux_raw_sys::general::O_ACCMODE,}

O_ACCMODE

pub const RWMODE: OFlags = Self{ bits: linux_raw_sys::general::O_RDONLY | linux_raw_sys::general::O_WRONLY | linux_raw_sys::general::O_RDWR,}

Similar to ACCMODE, but just includes the read/write flags, and no other flags.

Some implementations include O_PATH in O_ACCMODE, when sometimes we really just want the read/write bits. Caution is indicated, as the presence of O_PATH may mean that the read/write bits don’t have their usual meaning.

pub const APPEND: OFlags = Self{ bits: linux_raw_sys::general::O_APPEND,}

O_APPEND

pub const CREATE: OFlags = Self{ bits: linux_raw_sys::general::O_CREAT,}

O_CREAT

pub const DIRECTORY: OFlags = Self{ bits: linux_raw_sys::general::O_DIRECTORY,}

O_DIRECTORY

pub const DSYNC: OFlags = Self{ bits: linux_raw_sys::general::O_SYNC,}

O_DSYNC. Linux 2.6.32 only supports O_SYNC.

pub const EXCL: OFlags = Self{ bits: linux_raw_sys::general::O_EXCL,}

O_EXCL

pub const FSYNC: OFlags = Self{ bits: linux_raw_sys::general::O_SYNC,}

O_FSYNC. Linux 2.6.32 only supports O_SYNC.

pub const NOFOLLOW: OFlags = Self{ bits: linux_raw_sys::general::O_NOFOLLOW,}

O_NOFOLLOW

pub const NONBLOCK: OFlags = Self{ bits: linux_raw_sys::general::O_NONBLOCK,}

O_NONBLOCK

pub const RDONLY: OFlags = Self{ bits: linux_raw_sys::general::O_RDONLY,}

O_RDONLY

pub const WRONLY: OFlags = Self{ bits: linux_raw_sys::general::O_WRONLY,}

O_WRONLY

pub const RDWR: OFlags = Self{ bits: linux_raw_sys::general::O_RDWR,}

O_RDWR

pub const NOCTTY: OFlags = Self{ bits: linux_raw_sys::general::O_NOCTTY,}

O_NOCTTY

pub const RSYNC: OFlags = Self{ bits: linux_raw_sys::general::O_SYNC,}

O_RSYNC. Linux 2.6.32 only supports O_SYNC.

pub const SYNC: OFlags = Self{ bits: linux_raw_sys::general::O_SYNC,}

O_SYNC

pub const TRUNC: OFlags = Self{ bits: linux_raw_sys::general::O_TRUNC,}

O_TRUNC

pub const PATH: OFlags = Self{ bits: linux_raw_sys::general::O_PATH,}

O_PATH

pub const CLOEXEC: OFlags = Self{ bits: linux_raw_sys::general::O_CLOEXEC,}

O_CLOEXEC

pub const TMPFILE: OFlags = Self{ bits: linux_raw_sys::general::O_TMPFILE,}

O_TMPFILE

pub const NOATIME: OFlags = Self{ bits: linux_raw_sys::general::O_NOATIME,}

O_NOATIME

pub const DIRECT: OFlags = Self{ bits: linux_raw_sys::general::O_DIRECT,}

O_DIRECT

pub const fn empty() -> OFlags

Returns an empty set of flags.

pub const fn all() -> OFlags

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub const fn from_bits(bits: u32) -> Option<OFlags>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u32) -> OFlags

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: u32) -> OFlags

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 is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: OFlags) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: OFlags) -> bool

Returns true if all of the flags in other are contained within self.

pub fn insert(&mut self, other: OFlags)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: OFlags)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: OFlags)

Toggles the specified flags in-place.

pub fn set(&mut self, other: OFlags, value: bool)

Inserts or removes the specified flags depending on the passed value.

pub const fn intersection(self, other: OFlags) -> OFlags

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: OFlags) -> OFlags

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: OFlags) -> OFlags

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: OFlags) -> OFlags

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) -> OFlags

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.
