Struct ContractFeatures 

pub struct ContractFeatures { /* private fields */ }

Feature set of the deployed exchange smart contract.

Each flag guards a group of selectors/events introduced by a single release, so the SDK can index and snapshot a contract that has not been upgraded to the revision the SDK targets (crate::state::Exchange::revision).

Implementations

impl ContractFeatures

pub fn current() -> Self

Everything the SDK targets, with no version reported. Useful as a default for locally deployed contracts built from the SDK’s own ABI.

pub fn of(version: ContractVersion) -> Self

Feature set of a known contract version.

pub fn version(&self) -> Option<ContractVersion>

Version reported by the contract, if it exposes getContractVersion (v1.1.7.4+).

pub fn v2_state_getters(&self) -> bool

getPerpetualInfoV2 / getPositionV2 and the V2 position events (fundingSumScalingExp, priceResiduePNSQ16) are available.

pub fn keyed_fee_schedules(&self) -> bool

Keyed 8-tier fee schedules with per-account fee tiers are available (getPerpFeeSchedule, getFeeScheduleById, getAccountFeeTier and the FeeScheduleSet / DefaultPerpFeeScheduleSet / DefaultRwaFeeScheduleSet / PerpFeeSchedIdSet / AccountFeeTierSet events).

pub fn builder_attribution(&self) -> bool

Builder attribution is available (execOrderV2 and friends, getOrderV2 and the OrderRequestV2 / MakerOrderFilledV2 / TakerOrderFilledV2 events).

pub fn perpetual_discovery(&self) -> bool

The perpetual-existence bitmap is available (getPerpetualExistsBitmap), so the set of listed perpetuals can be discovered on-chain instead of being configured.
