Trait Backend 

pub trait Backend {
    // Required methods
    fn inspect(&self, container: &str) -> Result<bool, ExecError>;
    fn exec(&self, container: &str, args: &[&str]) -> Result<String, ExecError>;
    fn copy_to_container(
        &self,
        container: &str,
        host_path: &str,
        container_path: &str,
    ) -> Result<(), ExecError>;
}

Ported from the Backend interface in interface.go.

Required Methods

fn inspect(&self, container: &str) -> Result<bool, ExecError>

Reports whether the named container exists. A missing container returns Ok(false); only true execution errors yield Err.

fn exec(&self, container: &str, args: &[&str]) -> Result<String, ExecError>

Runs docker exec <container> <args...> and returns the captured stdout.

fn copy_to_container( &self, container: &str, host_path: &str, container_path: &str, ) -> Result<(), ExecError>

Copies a single host file to the given path inside the container via docker cp.

Dyn Compatibility

This trait is dyn compatible.

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