Function build_docker_state_snippet 

pub fn build_docker_state_snippet(container_name: &str) -> String

Shell fragment reading the container’s terminal state.

The four whitespace-free fields are split with set -- rather than the ${var%% *} / ${var##* } pair the two-field version used: those only ever reach the first and the last field. State.Error is read separately because it is free-form text that can contain spaces.
