Formats the value using the given formatter.

impl IntoPy<Py<PyAny>> for Expectancy

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

Performs the conversion.

impl PortfolioStatistic for Expectancy

type Item = f64

fn name(&self) -> String

fn calculate_from_realized_pnls( &self, realized_pnls: &[f64], ) -> Option<Self::Item>

fn calculate_from_returns(&self, returns: &Returns) -> Option<Self::Item>

fn calculate_from_orders( &self, orders: Vec<Box<dyn Order>>, ) -> Option<Self::Item>

fn calculate_from_positions(&self, positions: &[Position]) -> Option<Self::Item>

fn downsample_to_daily_bins(&self, returns: &Returns) -> Returns

fn calculate_std(&self, returns: &Returns) -> f64

impl PyClass for Expectancy

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for Expectancy

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<Expectancy>

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.

fn items_iter() -> PyClassItemsIter

fn doc(py: Python<'_>) -> PyResult<&'static CStr>

Rendered class doc

fn lazy_type_object() -> &'static LazyTypeObject<Self>

fn dict_offset() -> Option<isize>

fn weaklist_offset() -> Option<isize>

impl PyTypeInfo for Expectancy

const NAME: &'static str = "Expectancy"

Class name.

const MODULE: Option<&'static str> = _

Module name, if any.

fn type_object_raw(py: Python<'_>) -> *mut PyTypeObject

fn type_object_bound(py: Python<'_>) -> Bound<'_, PyType>

Returns the safe abstraction over the type object.

fn is_type_of_bound(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type or a subclass of this type.

fn is_exact_type_of_bound(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type.
