#[non_exhaustive]
pub struct ChildProcessSpec { /* private fields */ }

Command specification for a supervised child process.

Implementations

impl ChildProcessSpec

pub fn new(program: impl Into<OsString>) -> Self

Create a new child process specification.

pub fn arg(self, arg: impl Into<OsString>) -> Self

Add one command-line argument.

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

where I: IntoIterator<Item = S>, S: Into<OsString>,

Add multiple command-line arguments.

pub fn env(self, key: impl Into<OsString>, value: impl Into<OsString>) -> Self

Add one environment variable override.

pub fn current_dir(self, current_dir: impl Into<PathBuf>) -> Self

Set the child process working directory.

pub fn stdin_piped(self) -> Self

Pipe child stdin so the supervisor can write to it after spawn.

pub fn stdout_piped(self) -> Self

Pipe child stdout so the supervisor can read readiness output.

pub fn stderr_piped(self) -> Self

Pipe child stderr so the supervisor can forward log output.

pub fn kill_on_drop(self, kill_on_drop: bool) -> Self
