Implementations§

source§

impl OFlags

source

pub const ACCMODE: Self = _

O_ACCMODE

source

pub const RWMODE: Self = _

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

On some platforms, PATH may be included in ACCMODE, when sometimes we really just want the read/write bits. Caution is indicated, as the presence of PATH may mean that the read/write bits don’t have their usual meaning.

source

pub const APPEND: Self = _

O_APPEND

source

pub const CREATE: Self = _

O_CREAT

source

pub const DIRECTORY: Self = _

O_DIRECTORY

source

pub const DSYNC: Self = _

O_DSYNC.

source

pub const EXCL: Self = _

O_EXCL

source

pub const FSYNC: Self = _

source

pub const NONBLOCK: Self = _

O_NONBLOCK

source

pub const RDONLY: Self = _

O_RDONLY

source

pub const WRONLY: Self = _

O_WRONLY

source

pub const RDWR: Self = _

O_RDWR

This is not equal to RDONLY | WRONLY. It’s a distinct flag.

source

pub const NOCTTY: Self = _

O_NOCTTY

source

pub const RSYNC: Self = _

O_RSYNC.

source

pub const SYNC: Self = _

Get a flags value with all bits unset.

source

pub const fn all() -> Self

Get a flags value with all known bits set.

Convert from a bits value.

This method will return None if any unknown bits are set.

source

pub const fn from_bits_truncate(bits: c_uint) -> Self

Convert from a bits value, unsetting any unknown bits.

source

pub const fn from_bits_retain(bits: c_uint) -> Self

Convert from a bits value exactly.

source

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.

source

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

The bitwise or (|) of the bits in two flags values.

source

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.

The bitwise exclusive-or (^) of the bits in two flags values.

source

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

Call insert when value is true or remove when value is false.

The bitwise or (|) of the bits in two flags values.

source

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.

The bitwise exclusive-or (^) of the bits in two flags values.

source

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

source§

impl OFlags

source

pub const fn iter(&self) -> Iter<OFlags>

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

source

pub const fn iter_names(&self) -> IterNames<OFlags>

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.
