Struct MakerTakerFeeSchedule 

pub struct MakerTakerFeeSchedule {
    pub default: MakerTakerFeeRates,
    pub overrides: AHashMap<InstrumentId, MakerTakerFeeRates>,
}

Account-owned maker/taker fee schedule with exact instrument overrides.

Resolution is deterministic: an exact InstrumentId override wins, otherwise the default applies. Absent configuration is represented by the absence of a schedule (None at the owner), which is distinct from an explicit zero rate.

Fields

default: MakerTakerFeeRates

The default rates applied when no override matches.

overrides: AHashMap<InstrumentId, MakerTakerFeeRates>

Exact per-instrument rate overrides.

Implementations

impl MakerTakerFeeSchedule

pub fn new(maker: Decimal, taker: Decimal) -> Self

Creates a new schedule with explicit default rates and no overrides.

pub fn zero() -> Self

Creates a new explicit zero-fee schedule.

pub fn set_override( &mut self, instrument_id: InstrumentId, rates: MakerTakerFeeRates, )

Adds or replaces an exact instrument override.

pub fn rates_for(&self, instrument_id: InstrumentId) -> MakerTakerFeeRates

Returns the resolved rates for the given instrument.

pub fn rate_for( &self, instrument_id: InstrumentId, liquidity_side: LiquiditySide, ) -> Result<Decimal>

Returns the resolved rate for the given instrument and liquidity side.

Errors

Returns an error if liquidity_side is LiquiditySide::NoLiquiditySide.
