Struct PercentageFeeModel 

pub struct PercentageFeeModel {
    pub rate: Decimal,
}

Percentage-of-notional fee model for spot and futures exchanges.

total_fee = rate * price * quantity.abs()

Common for crypto spot/futures exchanges (e.g. Binance 0.1% taker fee).

Fields

rate: Decimal

Fee rate as a decimal fraction. Typical range is [0, 1]:

• 0.001 = 0.1% (common taker fee)
• 0.0005 = 0.05% (common maker fee)

No validation is performed; values outside [0, 1] are accepted but produce unusual fee amounts.

Trait Implementations

impl Clone for PercentageFeeModel

fn clone(&self) -> PercentageFeeModel

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PercentageFeeModel

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PercentageFeeModel

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FeeModel for PercentageFeeModel

fn compute_fee( &self, price: Decimal, quantity: Decimal, _contract_size: Decimal, ) -> Decimal

impl Hash for PercentageFeeModel

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for PercentageFeeModel

fn cmp(&self, other: &PercentageFeeModel) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PercentageFeeModel

fn eq(&self, other: &PercentageFeeModel) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for PercentageFeeModel

fn partial_cmp(&self, other: &PercentageFeeModel) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for PercentageFeeModel

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
