Continuous = 3

A Databento-specific symbology where one symbol may point to different instruments at different points of time, e.g. to always refer to the front month future.

Parent = 4

A Databento-specific symbology for referring to a group of symbols by one “parent” symbol, e.g. ES.FUT to refer to all ES futures.

Nasdaq = 5

Symbology for US equities using NASDAQ Integrated suffix conventions.

Cms = 6

Symbology for US equities using CMS suffix conventions.

Implementations

Convert the symbology type to its str representation.

Trait Implementations

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for SType

fn clone(&self) -> SType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SType

Available on crate feature serde only.

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for SType

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

Formats the value using the given formatter.

impl FromStr for SType

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl HasPyGilRef for SType

type AsRefTarget = PyCell<SType>

Utility type to make Py::as_ref work.

impl Hash for SType

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 IntoEnumIterator for SType

type Iterator = STypeIter

fn iter() -> STypeIter

impl IntoPy<Py<PyAny>> for SType

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

Performs the conversion.

impl PartialEq for SType

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PyClass for SType

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for SType

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<SType>

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.
