Struct InstrumentBalanceUpdate 

pub struct InstrumentBalanceUpdate<AssetKey = AssetIndex, InstrumentKey = InstrumentIndex> {
    pub instrument: InstrumentKey,
    pub balance: AssetBalanceUpdate<AssetKey>,
}

Live per-instrument isolated-margin balance update payload (the AccountEventKind::InstrumentBalanceUpdate counterpart of IsolatedInstrumentState).

Carries a point-in-time free/locked snapshot of one asset (the pair’s base or its quote) in the pair’s isolated sub-account — NOT a delta. It is the per-instrument counterpart of AccountEventKind::BalanceStreamUpdate: one event per asset, so a venue frame that lists only the asset that changed yields one event, and a frame listing both yields two. Apply each one to the (instrument, asset) it names and leave the pair’s other asset as it was. Which side it is follows from comparing AssetBalanceUpdate::asset with the instrument’s base and quote. The two events from one frame share a time_exchange but arrive separately, so a consumer can see one side updated before the other.

It carries no debt, so applying it keeps free/locked live while preserving any known per-asset debt (use Balance::apply_stream_update).

Fields

instrument: InstrumentKey

Instrument (isolated pair) the update applies to.

balance: AssetBalanceUpdate<AssetKey>

free/locked of one of the pair’s assets in its isolated sub-account.
