Trait Machine 

pub trait Machine {
    // Required methods
    fn installed(&self, program: &str) -> bool;
    fn docker_running(&self) -> bool;
    fn os(&self) -> String;
    fn run(
        &self,
        program: &str,
        args: &[&str],
        dir: &Path,
    ) -> Result<(), String>;
    fn output(
        &self,
        program: &str,
        args: &[&str],
        dir: &Path,

    ) -> Result<String, String>;
}

What the CLI needs to know about, or do on, the machine.

Required Methods

fn installed(&self, program: &str) -> bool

Whether a program answers --version.

fn docker_running(&self) -> bool

Whether the Docker daemon answers.

fn os(&self) -> String

The operating system, as prompts name it: macOS, Windows, Ubuntu 24.04.

fn run(&self, program: &str, args: &[&str], dir: &Path) -> Result<(), String>

Runs a program in dir, its output hidden; Err holds what it printed on error.

fn output( &self, program: &str, args: &[&str], dir: &Path, variables: &[(String, String)], ) -> Result<String, String>

Runs a program in dir with more environment variables, and returns what it printed.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
