Struct glib::SpawnFlags

pub struct SpawnFlags { /* fields omitted */ }

Flags passed to g_spawn_sync(), spawn_async() and g_spawn_async_with_pipes().

Implementations

impl SpawnFlags

pub const DEFAULT: SpawnFlags

no flags, default behaviour

pub const LEAVE_DESCRIPTORS_OPEN: SpawnFlags

the parent’s open file descriptors will be inherited by the child; otherwise all descriptors except stdin, stdout and stderr will be closed before calling exec() in the child.

pub const DO_NOT_REAP_CHILD: SpawnFlags

the child will not be automatically reaped; you must use g_child_watch_add() yourself (or call waitpid() or handle SIGCHLD yourself), or the child will become a zombie.

pub const SEARCH_PATH: SpawnFlags

argv[0] need not be an absolute path, it will be looked for in the user’s PATH.

pub const STDOUT_TO_DEV_NULL: SpawnFlags

the child’s standard output will be discarded, instead of going to the same location as the parent’s standard output.

pub const STDERR_TO_DEV_NULL: SpawnFlags

the child’s standard error will be discarded.

pub const CHILD_INHERITS_STDIN: SpawnFlags

the child will inherit the parent’s standard input (by default, the child’s standard input is attached to /dev/null).

pub const FILE_AND_ARGV_ZERO: SpawnFlags

the first element of argv is the file to execute, while the remaining elements are the actual argument vector to pass to the file. Normally g_spawn_async_with_pipes() uses argv[0] as the file to execute, and passes all of argv to the child.

pub const SEARCH_PATH_FROM_ENVP: SpawnFlags

if argv[0] is not an absolute path, it will be looked for in the PATH from the passed child environment. Since: 2.34

pub const CLOEXEC_PIPES: SpawnFlags

create all pipes with the O_CLOEXEC flag set. Since: 2.40

pub const fn empty() -> SpawnFlags

Returns an empty set of flags

pub const fn all() -> SpawnFlags

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

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

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) -> SpawnFlags

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

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

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

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: SpawnFlags) -> bool

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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