Struct FeeScheduleRegistry 

pub struct FeeScheduleRegistry { /* private fields */ }

Every fee schedule the exchange resolves fees from, keyed by FeeScheduleKey.

Populated on snapshotting with the two exchange-wide schedules (FeeScheduleKey::Default and FeeScheduleKey::RwaDefault) plus the custom schedule of every perpetual the snapshot tracks, then kept up to date by FeeScheduleSet / DefaultPerpFeeScheduleSet / DefaultRwaFeeScheduleSet.

The registry holds the rates; which schedule a perpetual resolves its fees from is the perpetual’s own state (the key of crate::state::Perpetual::fee_schedule), moved only by PerpFeeSchedIdSet. Rewriting a schedule therefore reaches a perpetual only if that perpetual is currently pointing at it.

Implementations

impl FeeScheduleRegistry

pub fn default_schedule(&self) -> FeeSchedule

Exchange-wide default schedule, shared by every perpetual contract that has not been repointed at another one.

pub fn rwa_default_schedule(&self) -> FeeSchedule

Exchange-wide default schedule for real-world assets.

pub fn custom_schedules(&self) -> &HashMap<PerpetualId, FeeSchedule>

Custom schedules, by the id of the perpetual contract each is keyed by.

Covers the perpetuals known when the snapshot was built, plus any picked up from a FeeScheduleSet since; a perpetual listed after the snapshot appears here only once its own schedule is written.

pub fn schedules(&self) -> impl Iterator<Item = FeeSchedule>

Every registered schedule: the exchange-wide default, the RWA default, then the custom ones ordered by the perpetual id each is keyed by.

pub fn get(&self, key: FeeScheduleKey) -> Option<FeeSchedule>

Schedule registered under the given key, None for a custom schedule that has never been observed.
