Executes CommandSpecs.

Required Methods§

Source

fn run( &self, spec: &CommandSpec, io: IoPolicy, ) -> Result<CommandOutput, ProcessError>

Runs the command to completion.

Source

fn spawn_detached(&self, spec: &CommandSpec) -> Result<(), ProcessError>

Starts the command without waiting for it to finish.

§Errors

Returns ProcessError::NotFound or ProcessError::Spawn if the program could not be started.

Provided Methods§

Source

fn run_checked( &self, spec: &CommandSpec, io: IoPolicy, ) -> Result<CommandOutput, ProcessError>

Runs the command and fails if it exits unsuccessfully.
