pub struct StdioFlags { /* private fields */ }
Expand description

Flags specifying how a stdio should be transmitted to the child process.

Implementations§

source§

impl StdioFlags

source

pub const IGNORE: StdioFlags = _

No file descriptor will be provided (or redirected to /dev/null if it is fd 0, 1 or 2).

source

pub const CREATE_PIPE: StdioFlags = _

Open a new pipe into data.stream, per the flags below. The data.stream field must point to a PipeHandle object that has been initialized with new, but not yet opened or connected.

source

pub const INHERIT_FD: StdioFlags = _

The child process will be given a duplicate of the parent’s file descriptor given by data.fd.

source

pub const INHERIT_STREAM: StdioFlags = _

The child process will be given a duplicate of the parent’s file descriptor being used by the stream handle given by data.stream.

source

pub const READABLE_PIPE: StdioFlags = _

When UV_CREATE_PIPE is specified, UV_READABLE_PIPE and UV_WRITABLE_PIPE determine the direction of flow, from the child process’ perspective. Both flags may be specified to create a duplex data stream.

source

pub const WRITABLE_PIPE: StdioFlags = _

source

pub const OVERLAPPED_PIPE: StdioFlags = _

Open the child pipe handle in overlapped mode on Windows. On Unix it is silently ignored.

source

pub const fn empty() -> StdioFlags

Returns an empty set of flags

source

pub const fn all() -> StdioFlags

Returns the set containing all flags.

source

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

source

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

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

source

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

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

source

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

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

source

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

source

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

source

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

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

source

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

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

source

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

Inserts the specified flags in-place.

source

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

Removes the specified flags in-place.

source

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

Toggles the specified flags in-place.

source

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

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