[−][src]Struct procspawn::PoolBuilder
Utility to configure a pool.
This requires the pool
feature.
Methods
impl PoolBuilder
[src]
pub fn env<K, V>(&mut self, key: K, val: V) -> &mut Self where
K: AsRef<OsStr>,
V: AsRef<OsStr>,
[src]
K: AsRef<OsStr>,
V: AsRef<OsStr>,
Set an environment variable in the spawned process.
Equivalent to Command::env
pub fn envs<I, K, V>(&mut self, vars: I) -> &mut Self where
I: IntoIterator<Item = (K, V)>,
K: AsRef<OsStr>,
V: AsRef<OsStr>,
[src]
I: IntoIterator<Item = (K, V)>,
K: AsRef<OsStr>,
V: AsRef<OsStr>,
Set environment variables in the spawned process.
Equivalent to Command::envs
pub fn env_remove<K: AsRef<OsStr>>(&mut self, key: K) -> &mut Self
[src]
Removes an environment variable in the spawned process.
Equivalent to Command::env_remove
pub fn env_clear(&mut self) -> &mut Self
[src]
Clears all environment variables in the spawned process.
Equivalent to Command::env_clear
pub fn uid(&mut self, id: u32) -> &mut Self
[src]
Sets the child process's user ID. This translates to a
setuid
call in the child process. Failure in the setuid
call will cause the spawn to fail.
Unix-specific extension only available on unix.
Equivalent to std::os::unix::process::CommandExt::uid
pub fn gid(&mut self, id: u32) -> &mut Self
[src]
Similar to uid
, but sets the group ID of the child process. This has
the same semantics as the uid
field.
Unix-specific extension only available on unix.
Equivalent to std::os::unix::process::CommandExt::gid
pub unsafe fn pre_exec<F>(&mut self, f: F) -> &mut Self where
F: FnMut() -> Result<()> + Send + Sync + 'static,
[src]
F: FnMut() -> Result<()> + Send + Sync + 'static,
Schedules a closure to be run just before the exec
function is
invoked.
Safety
This method is inherently unsafe. See the notes of the unix command ext for more information.
Equivalent to std::os::unix::process::CommandExt::pre_exec
pub fn disable_stdin(&mut self) -> &mut Self
[src]
Redirects stdin to /dev/null
.
pub fn disable_stdout(&mut self) -> &mut Self
[src]
Redirects stdout to /dev/null
.
pub fn disable_stderr(&mut self) -> &mut Self
[src]
Redirects stderr to /dev/null
.
pub fn build(&mut self) -> Result<Pool, SpawnError>
[src]
Creates the pool.
