Enum MarginSideEffect 

Source 
pub enum MarginSideEffect {
    AutoBorrowRepay,
    NoBorrow,
}
Expand description

Margin sideEffectType borrow/repay policy, fixed once per BinanceMargin client.

Only the two intent-agnostic modes are exposed as client-level variants. The borrow-vs-repay decision derives from open/close direction — position state the library deliberately does not track — so the venue is left to infer it from the account’s loan state. The per-order modes (MARGIN_BUY / AUTO_REPAY) are intentionally not modelled here; they belong to a future generic per-order RequestOpen::margin_effect field that all margin adapters would map, added only when a venue with genuine per-order borrow intent (e.g. another CEX margin) appears. Mixed borrow appetite on a single venue today means running two clients (one per mode).

The Serialize/Deserialize wire form is the config-file value ("auto_borrow_repay" / "no_borrow"); this is distinct from the Binance API value returned by as_binance_str ("AUTO_BORROW_REPAY" / "NO_SIDE_EFFECT").

Variants§

§

AutoBorrowRepay

AUTO_BORROW_REPAY — the venue borrows on entry and repays on close as needed.

§Warning

This is the default because it makes shorting work out of the box, but it means a mis-sized order silently takes on debt: an order larger than the free balance borrows the shortfall without any further opt-in (same footgun class as RequestOpen::reduce_only). Use MarginSideEffect::NoBorrow for a client that must never silently borrow.

§

NoBorrow

NO_SIDE_EFFECT — never borrow or repay; orders that would require borrowing are rejected by the venue. The conservative opt-out from the AutoBorrowRepay silent-borrow behaviour.
