Implementations

impl LinuxPipeFlags

Flags

pub const NONE: Self

No pipe flags.

pub const CLOEXEC: Self

Close pipe descriptors during exec.

pub const NONBLOCK: Self

Open both pipe ends in nonblocking mode.

pub const DIRECT: Self

Use packet-mode pipe I/O.

This corresponds to Linux O_DIRECT for pipes.

pub const NOTIFICATION: Self

Create a notification pipe.

This reuses the same raw bit as O_EXCL, but in the pipe2 context it means O_NOTIFICATION_PIPE.

impl LinuxPipeFlags

Methods

pub const fn new() -> Self

Returns an empty flag set.

pub const fn from_bits(bits: c_int) -> Self

Returns flags from raw Linux bits.

pub const fn default_exec_safe() -> Self

Returns the default pipe flags.

The default closes pipe descriptors during exec.

pub const fn bits(self) -> c_int

Returns the raw Linux bits.

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

Returns whether all flags in other are present.

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

Returns whether any flag in other is present.

pub const fn with(self, other: Self) -> Self

Returns this flag set with other included.

pub const fn without(self, other: Self) -> Self

Returns this flag set without other.

pub const fn close_on_exec(self) -> Self

Includes close-on-exec.

pub const fn inherit_on_exec(self) -> Self

Allows inheritance across exec.

pub const fn nonblock(self) -> Self

Includes nonblocking mode.

pub const fn direct(self) -> Self

Includes packet-mode pipe I/O.

pub const fn notification(self) -> Self

Includes notification-pipe mode.
