pub struct SubprocessFlags(/* private fields */);
Expand description
Flags to define the behaviour of a #GSubprocess.
Note that the default for stdin is to redirect from /dev/null
. For
stdout and stderr the default are for them to inherit the
corresponding descriptor from the calling process.
Note that it is a programmer error to mix ‘incompatible’ flags. For
example, you may not request both STDOUT_PIPE
and
STDOUT_SILENCE
.
Implementations§
source§impl SubprocessFlags
impl SubprocessFlags
sourcepub const STDIN_PIPE: Self = _
pub const STDIN_PIPE: Self = _
create a pipe for the stdin of the spawned process that can be accessed with g_subprocess_get_stdin_pipe().
sourcepub const STDIN_INHERIT: Self = _
pub const STDIN_INHERIT: Self = _
stdin is inherited from the calling process.
sourcepub const STDOUT_PIPE: Self = _
pub const STDOUT_PIPE: Self = _
create a pipe for the stdout of the spawned process that can be accessed with g_subprocess_get_stdout_pipe().
sourcepub const STDOUT_SILENCE: Self = _
pub const STDOUT_SILENCE: Self = _
silence the stdout of the spawned
process (ie: redirect to /dev/null
).
sourcepub const STDERR_PIPE: Self = _
pub const STDERR_PIPE: Self = _
create a pipe for the stderr of the spawned process that can be accessed with g_subprocess_get_stderr_pipe().
sourcepub const STDERR_SILENCE: Self = _
pub const STDERR_SILENCE: Self = _
silence the stderr of the spawned
process (ie: redirect to /dev/null
).
sourcepub const STDERR_MERGE: Self = _
pub const STDERR_MERGE: Self = _
merge the stderr of the spawned process with whatever the stdout happens to be. This is a good way of directing both streams to a common log file, for example.
sourcepub const INHERIT_FDS: Self = _
pub const INHERIT_FDS: Self = _
spawned processes will inherit the file descriptors of their parent, unless those descriptors have been explicitly marked as close-on-exec. This flag has no effect over the “standard” file descriptors (stdin, stdout, stderr).
sourcepub const SEARCH_PATH_FROM_ENVP: Self = _
Available on crate feature v2_72
only.
pub const SEARCH_PATH_FROM_ENVP: Self = _
v2_72
only.if path searching is
needed when spawning the subprocess, use the PATH
in the launcher
environment. (Since: 2.72)
source§impl SubprocessFlags
impl SubprocessFlags
sourcepub const fn bits(&self) -> u32
pub const fn bits(&self) -> u32
Get the underlying bits value.
The returned value is exactly the bits set in this flags value.
sourcepub const fn from_bits(bits: u32) -> Option<Self>
pub const fn from_bits(bits: u32) -> Option<Self>
Convert from a bits value.
This method will return None
if any unknown bits are set.
sourcepub const fn from_bits_truncate(bits: u32) -> Self
pub const fn from_bits_truncate(bits: u32) -> Self
Convert from a bits value, unsetting any unknown bits.
sourcepub const fn from_bits_retain(bits: u32) -> Self
pub const fn from_bits_retain(bits: u32) -> Self
Convert from a bits value exactly.
sourcepub fn from_name(name: &str) -> Option<Self>
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.
sourcepub const fn intersects(&self, other: Self) -> bool
pub const fn intersects(&self, other: Self) -> bool
Whether any set bits in a source flags value are also set in a target flags value.
sourcepub const fn contains(&self, other: Self) -> bool
pub const fn contains(&self, other: Self) -> bool
Whether all set bits in a source flags value are also set in a target flags value.
sourcepub fn remove(&mut self, other: Self)
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.
sourcepub fn toggle(&mut self, other: Self)
pub fn toggle(&mut self, other: Self)
The bitwise exclusive-or (^
) of the bits in two flags values.
sourcepub fn set(&mut self, other: Self, value: bool)
pub fn set(&mut self, other: Self, value: bool)
Call insert
when value
is true
or remove
when value
is false
.
sourcepub const fn intersection(self, other: Self) -> Self
pub const fn intersection(self, other: Self) -> Self
The bitwise and (&
) of the bits in two flags values.
sourcepub const fn union(self, other: Self) -> Self
pub const fn union(self, other: Self) -> Self
The bitwise or (|
) of the bits in two flags values.
sourcepub const fn difference(self, other: Self) -> Self
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.
sourcepub const fn symmetric_difference(self, other: Self) -> Self
pub const fn symmetric_difference(self, other: Self) -> Self
The bitwise exclusive-or (^
) of the bits in two flags values.
sourcepub const fn complement(self) -> Self
pub const fn complement(self) -> Self
The bitwise negation (!
) of the bits in a flags value, truncating the result.
source§impl SubprocessFlags
impl SubprocessFlags
sourcepub const fn iter(&self) -> Iter<SubprocessFlags>
pub const fn iter(&self) -> Iter<SubprocessFlags>
Yield a set of contained flags values.
Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.
sourcepub const fn iter_names(&self) -> IterNames<SubprocessFlags>
pub const fn iter_names(&self) -> IterNames<SubprocessFlags>
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.
