Struct BetPosition

pub struct BetPosition { /* private fields */ }

A position comprising one or more bets.

Implementations

impl BetPosition

pub fn price(&self) -> Decimal

Returns the position’s price.

pub fn exposure(&self) -> Decimal

Returns the position’s exposure.

pub fn realized_pnl(&self) -> Decimal

Returns the position’s realized profit and loss.

pub fn bets(&self) -> &[Bet]

Returns a reference to the position’s bets.

pub fn side(&self) -> Option<BetSide>

Returns the overall side of the position.

If exposure is positive the side is BACK; if negative, LAY; if zero, None.

pub fn as_bet(&self) -> Option<Bet>

Converts the current position into a single bet, if possible.

pub fn add_bet(&mut self, bet: Bet)

Adds a bet to the position, adjusting exposure and realized PnL.

pub fn position_increase(&mut self, bet: &Bet)

Increases the position with the provided bet.

pub fn position_decrease(&mut self, bet: &Bet)

Decreases the position with the provided bet.

This method calculates the realized PnL by comparing the incoming bet with a corresponding bet derived from the current position.

pub fn unrealized_pnl(&self, price: Decimal) -> Decimal

Calculates the unrealized profit and loss given a current price.

pub fn total_pnl(&self, price: Decimal) -> Decimal

Returns the total profit and loss (realized plus unrealized) given a current price.

pub fn flattening_bet(&self, price: Decimal) -> Option<Bet>

Creates a bet that would flatten (neutralize) the current position.

pub fn reset(&mut self)

Resets the bet position to its initial state.

impl IntoPy<Py<PyAny>> for BetPosition

fn into_py(self, py: Python<'_>) -> PyObject

👎Deprecated since 0.23.0: IntoPy is going to be replaced by IntoPyObject. See the migration guide (https://pyo3.rs/v0.23.0/migration) for more information.

Performs the conversion.

impl<'py> IntoPyObject<'py> for BetPosition

type Target = BetPosition

The Python output type

type Output = Bound<'py, <BetPosition as IntoPyObject<'py>>::Target>

The smart pointer type to use.

type Error = PyErr

The type returned in the event of a conversion error.

Performs the conversion.

impl PyClass for BetPosition

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for BetPosition

const IS_BASETYPE: bool = false

#[pyclass(subclass)]

const IS_SUBCLASS: bool = false

#[pyclass(extends=…)]

const IS_MAPPING: bool = false

#[pyclass(mapping)]

const IS_SEQUENCE: bool = false

#[pyclass(sequence)]

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<BetPosition>

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.
