Struct DtactCommand 

pub struct DtactCommand(/* private fields */);

Async-friendly wrapper over std::process::Command. Builder methods mirror std::process::Command’s own naming.

Implementations

impl DtactCommand

pub fn new(program: impl AsRef<OsStr>) -> Self

Start building a command that will run program.

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

Append a single argument.

pub fn args<I, S>(&mut self, args: I) -> &mut Self

where I: IntoIterator<Item = S>, S: AsRef<OsStr>,

Append multiple arguments at once.

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

Set an environment variable for the child process.

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

Set the working directory the child process is spawned in.

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

Configure how the child’s stdin is set up (inherit/pipe/null).

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

Configure how the child’s stdout is set up (inherit/pipe/null).

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

Configure how the child’s stderr is set up (inherit/pipe/null).

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

Spawn the child process. A direct synchronous syscall — see the module doc for why this isn’t dispatched to the pool.

Errors

Returns whatever std::process::Command::spawn returns: most commonly io::ErrorKind::NotFound if program isn’t on PATH/ doesn’t exist, or PermissionDenied if it exists but isn’t executable by the current user.
