Trait Implementations§

Source§

impl RuntimeCommand for AsyncStdCommand

Source§

type Runtime = AsyncStdGlobalRuntime

An async runtime.
Source§

fn new(program: impl AsRef<OsStr>) -> Self
where Self: Sized,

Constructs a new RuntimeCommand for launching the program at path program, with the following default configuration: Read more
Source§

fn arg(&mut self, arg: impl AsRef<OsStr>) -> &mut Self

Adds an argument to pass to the program.
Source§

fn args(&mut self, args: impl Iterator<Item = impl AsRef<OsStr>>) -> &mut Self

Adds multiple arguments to pass to the program.
Source§

fn env(&mut self, key: impl AsRef<OsStr>, value: impl AsRef<OsStr>) -> &mut Self

Inserts or updates an explicit environment variable mapping. Read more
Source§

fn envs( &mut self, vars: impl Iterator<Item = (impl AsRef<OsStr>, impl AsRef<OsStr>)>, ) -> &mut Self

Inserts or updates multiple explicit environment variable mappings. Read more
Source§

fn env_remove(&mut self, key: impl AsRef<OsStr>) -> &mut Self

Removes an explicitly set environment variable and prevents inheriting it from a parent process. Read more
Source§

fn env_clear(&mut self) -> &mut Self

Clears all explicitly set environment variables and prevents inheriting any parent process environment variables. Read more
Source§

fn current_dir(&mut self, dir: impl AsRef<Path>) -> &mut Self

Sets the working directory for the child process. Read more
Source§

fn stdin(&mut self, stdin: impl Into<Stdio>) -> &mut Self

Configuration for the child process’s standard input (stdin) handle. Read more
Source§

fn stdout(&mut self, stdout: impl Into<Stdio>) -> &mut Self

Configuration for the child process’s standard output (stdout) handle. Read more
Source§

fn stderr(&mut self, stderr: impl Into<Stdio>) -> &mut Self

Configuration for the child process’s standard error (stderr) handle. Read more
Source§

fn spawn(&mut self) -> Result<<Self::Runtime as ProcessRuntime>::Child>

Executes the command as a child process, returning a handle to it. Read more
Source§

fn output(&mut self) -> impl Future<Output = Result<Output>> + Send

Executes the command as a child process, waiting for it to finish and collecting all of its output. Read more
Source§

fn status(&mut self) -> impl Future<Output = Result<ExitStatus>> + Send

Executes a command as a child process, waiting for it to finish and collecting its status. Read more
Source§

fn uid(&mut self, uid: u32) -> &mut Self

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. Read more
Source§

fn gid(&mut self, gid: u32) -> &mut Self

Similar to uid, but sets the group ID of the child process. This has the same semantics as the uid field.
Source§

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

Schedules a closure to be run just before the exec function is invoked. Read more
