Trait CommandRunner 

pub trait CommandRunner: Send + Sync {
    // Required method
    fn run_script(
        &self,
        script_path: &str,
        stdin_content: &str,
        env_vars: &[(&str, &str)],
    ) -> Result<Output>;
}

Trait for running shell commands.

Enables mocking in tests to verify error handling without actual failures. Uses generics for zero-cost abstraction in production code.

Required Methods

fn run_script( &self, script_path: &str, stdin_content: &str, env_vars: &[(&str, &str)], ) -> Result<Output>

• stdin_content - Content to write to the script’s stdin
