Struct Options 

pub struct Options {
    pub log_level: Option<LogLevel>,
    pub stderr_log_level: Option<LogLevel>,
    pub failure_log_level: Option<LogLevel>,
    pub disable_streaming: bool,
    pub stdin: Option<Box<dyn Read + Send>>,
    pub env: Option<Vec<String>>,
    pub timeout: Option<Duration>,
    pub log_writer: Option<Arc<Mutex<Vec<u8>>>>,
}

Ported from Options in exec.go.

timeout has no Go counterpart on Options itself — Go threads a deadline through the ambient context.Context argument every function in this package takes. This port has no ambient context (see the “Design notes” section of PORT_NOTES.md), so a deadline is passed explicitly here instead. This is a disclosed deviation, not a silent behavioral gap.

log_writer corresponds to Go’s Logger *slog.Logger field. Go’s tests inject a *slog.Logger writing to an in-memory buffer (captureLogger) to assert on the single “command error”/“command completed” completion record logRunCompletion emits after a run finishes. This port doesn’t thread a full tracing::Dispatch through here (that would need tracing::dispatcher::with_default’s thread-local guard held across the .await points in run_async, which doesn’t survive a task being moved between worker threads) – instead log_writer, when set, receives that same one completion line, formatted directly by log_completion. When None (the default), no completion line is emitted at all, which is a disclosed narrowing from Go’s “falls back to slog.Default()” behavior: this port has no equivalent of a mutable, ambient global default logger to fall back to (see this crate’s other “no reassignable package-level state” deviations), and no caller outside the ported tests currently needs one.
