Struct Bet

pub struct Bet { /* private fields */ }

A bet in a betting market.

Implementations

impl Bet

pub fn new(price: Decimal, stake: Decimal, side: BetSide) -> Self

Creates a new Bet instance.

pub fn price(&self) -> Decimal

Returns the bet’s price.

pub fn stake(&self) -> Decimal

Returns the bet’s stake.

pub fn side(&self) -> BetSide

Returns the bet’s side.

pub fn from_stake_or_liability( price: Decimal, volume: Decimal, side: BetSide, ) -> Self

Creates a bet from a stake or liability depending on the bet side.

For BetSide::Back this calls Self::from_stake and for BetSide::Lay it calls Self::from_liability.

pub fn from_stake(price: Decimal, stake: Decimal, side: BetSide) -> Self

Creates a bet from a given stake.

pub fn from_liability(price: Decimal, liability: Decimal, side: BetSide) -> Self

Creates a bet from a given liability.

Panics

Panics if the side is not BetSide::Lay.

pub fn exposure(&self) -> Decimal

Returns the bet’s exposure.

For BACK bets, exposure is positive; for LAY bets, it is negative.

pub fn liability(&self) -> Decimal

Returns the bet’s liability.

For BACK bets, liability equals the stake; for LAY bets, it is stake multiplied by (price - 1).

pub fn profit(&self) -> Decimal

Returns the bet’s profit.

For BACK bets, profit is stake * (price - 1); for LAY bets it equals the stake.

pub fn outcome_win_payoff(&self) -> Decimal

Returns the outcome win payoff.

For BACK bets this is the profit; for LAY bets it is the negative liability.

pub fn outcome_lose_payoff(&self) -> Decimal

Returns the outcome lose payoff.

For BACK bets this is the negative liability; for LAY bets it is the profit.

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

Returns the hedging stake given a new price.

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

Creates a hedging bet for a given price.

Trait Implementations

impl Clone for Bet

fn clone(&self) -> Bet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Bet

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

Formats the value using the given formatter.

impl Display for Bet

impl IntoPy<Py<PyAny>> for Bet

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 Bet

type Target = Bet

The Python output type

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

The smart pointer type to use.

type Error = PyErr

The type returned in the event of a conversion error.

fn into_pyobject( self, py: Python<'py>, ) -> Result<<Self as IntoPyObject<'_>>::Output, <Self as IntoPyObject<'_>>::Error>

Performs the conversion.

impl PartialEq for Bet

fn eq(&self, other: &Bet) -> 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 PyClass for Bet

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for Bet

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<Bet>

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.
