Struct AskpassHelper 

pub struct AskpassHelper { /* private fields */ }

Spawns program per call with a single prompt argument and reads the username or password from stdout.

program is the raw command string, split on whitespace the same way upstream’s subprocess.ExecCommand shells expand it: the first token is the executable and subsequent tokens are passed as additional args before the prompt.
