Fee Parameters.
Implementations§
Source§impl<T> FeeParams<T>
impl<T> FeeParams<T>
Sourcepub fn builder() -> FeeParamsBuilder<T, ((), (), (), ())>
pub fn builder() -> FeeParamsBuilder<T, ((), (), (), ())>
Create a builder for building FeeParams.
On the builder, call .positive_impact_fee_factor(...), .negative_impact_fee_factor(...), .fee_receiver_factor(...), .discount_factor(...)(optional) to set the values of the fields.
Finally, call .build() to create the instance of FeeParams.

Sourcepub fn with_discount_factor(self, factor: T) -> Self
pub fn with_discount_factor(self, factor: T) -> Self
Set discount factor.
Sourcepub fn receiver_factor(&self) -> &T
pub fn receiver_factor(&self) -> &T
Get receiver factor.

pub fn fee<const DECIMALS: u8>(
&self,
is_positive_impact: bool,
amount: &T,

amount: &T,
) -> Option<(T, Fees<T>)>where
T: FixedPointOps<DECIMALS>,
Apply fees to amount.
DECIMALSis the decimals of the parameters.
Returns None if the computation fails, otherwise amount after fees and the fees are returned.

size_delta_usd: &T,
is_positive_impact: bool,
) -> Result<PositionFees<T>>where
T: FixedPointOps<DECIMALS>,
