pub fn options_from_env(value: &str) -> Vec<(String, String)>Expand description
Parse the AMPL pounce_options environment variable into
(key, value) option pairs.
AMPL passes solver directives through a <solver>_options env var
(here pounce_options): a whitespace-separated list of key=value
tokens — the same key=value grammar pounce accepts as positional CLI
options. Tokens without an = (AMPL’s rarer keyword value spelling)
are skipped rather than guessed at, matching the CLI parser, which has
no key value form either. The caller applies these before the
command-line key=value options so an explicit CLI flag wins.
