Struct Command

pub struct Command<'a> { /* private fields */ }

Implementations

impl<'a> Command<'a>

pub fn new(bin: &'a UnixStr) -> Result<Self>

Constructs a new command, setting the first argument as the binary’s name

Errors

If the string is not C string compatible

pub fn env(&mut self, env: UnixString) -> &mut Self

Errors

If the string is not C string compatible

pub fn envs(&mut self, envs: impl Iterator<Item = UnixString>) -> &mut Self

Errors

If the string is not C string compatible

pub fn arg(&mut self, arg: &'a UnixStr) -> &mut Self

Errors

If the string is not C string compatible

pub fn args(&mut self, args: impl Iterator<Item = &'a UnixStr>) -> &mut Self

Errors

If the string is not C string compatible

pub unsafe fn pre_exec<F: FnMut() -> Result<()> + Send + Sync + 'static>( &mut self, f: F, ) -> &mut Self

A function to run after forking off the process but before the exec call

Safety

Some things, such as some memory access will immediately cause UB, keep it simple, short, and sweet.

pub fn cwd(&mut self, dir: &'a UnixStr) -> &mut Self

Errors

If the string is not C string compatible

pub fn uid(&mut self, id: UidT) -> &mut Self

pub fn gid(&mut self, id: GidT) -> &mut Self

pub fn pgroup(&mut self, pgroup: PidT) -> &mut Self

pub fn stdin(&mut self, stdin: Stdio) -> &mut Self

pub fn stdout(&mut self, stdout: Stdio) -> &mut Self

pub fn stderr(&mut self, stderr: Stdio) -> &mut Self

pub fn spawn(&mut self) -> Result<Child>

Spawns a new child process from this command.

Errors

pub fn exec(&mut self) -> Error
