Required Methods

fn from_script(_: &str) -> Self

Use SHELL to create a command from a shell script On unix, the empty string is given to $0 so that subsequent args are fed to the script directly. On windows (todo)

fn with_arg<S: AsRef<OsStr>>(self, _: S) -> Self

fn with_args<I, S>(self, _: I) -> Self

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

fn display(&self) -> String

Display the command. Does not escape arguments.

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

Detach the command. Does nothing on unsupported platforms (not windows or unix).

fn spawn_detached(&mut self) -> Option<Child>

One-off spawn executable. Logs the command in debug builds. Prints error.

fn spawn_piped(&mut self) -> Result<ChildStdout, StringError>

Spawn command with piped stdout. Debug logs the command.

fn success(&mut self) -> bool

Naive check of whether a command succeeds. (i.e. health check).

fn _exec(&mut self) -> !

Platform-agnostic exec the command.

Logs and displays errors.

fn _spawn(&mut self) -> Option<Child>

Spawn the command, with trace and error logging.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
