Struct PyDemand 

pub(crate) struct PyDemand {
    pub(crate) inner: Demand,
}

What a book needs from outside to price on a market: quote strips by template, fixings by series and date, FX spots by pair — and the curves no recipe builds. MarketContext.demand(book) derives one; a source’s fetch(demand, as_of) answers it.

Fields

inner: Demand

Implementations

impl PyDemand

fn asks(&self) -> bool

Whether this demand asks a source for anything: a strip, a fixing or a spot. An async caller skips its fetch where it does not.

fn as_of(&self) -> NaiveDate

The date the market is as of.

fn reporting(&self) -> Option<String>

The currency the book reports in, where it has one.

fn keys(&self) -> Vec<String>

The collateral keys the snapshot builds, in build order.

fn strips(&self) -> PyRecords

The quote strips: key (the collateral key whose recipe names the template) and template.

fn fixings(&self) -> PyRecords

The fixings a valuation reads: series and date.

fn fx(&self) -> Vec<String>

The FX spots, each in its conventional quotation (EUR/USD).

fn unresolved(&self) -> PyRecords

The curves the book reads that no recipe builds: curve and reason.

fn out_of_scope(&self) -> Vec<String>

What the book declares that sources do not serve yet.

fn recipe_ask(&self) -> PyRecipeAsk

The keys a recipe source is asked about.

fn __repr__(&self) -> String

Trait Implementations

impl Clone for PyDemand

fn clone(&self) -> PyDemand

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DerefToPyAny for PyDemand

impl IntoPy<Py<PyAny>> for PyDemand

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

Performs the conversion.

impl PyClass for PyDemand

type Frozen = True

Whether the pyclass is frozen.

impl PyClassImpl for PyDemand

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<PyDemand>

This handles following two situations:

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

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<'a, 'py> PyFunctionArgument<'a, 'py> for &'a PyDemand

type Holder = Option<PyRef<'py, PyDemand>>

fn extract( obj: &'a Bound<'py, PyAny>, holder: &'a mut Self::Holder, ) -> PyResult<Self>

impl PyMethods<PyDemand> for PyClassImplCollector<PyDemand>

fn py_methods(self) -> &'static PyClassItems

impl PyTypeInfo for PyDemand

const NAME: &'static str = "Demand"

Class name.

const MODULE: Option<&'static str>

Module name, if any.

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

Returns the PyTypeObject instance for this type.

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.
