Enum dbn::enums::Action

#[repr(u8)]
pub enum Action {
    Modify = 77,
    Trade = 84,
    Fill = 70,
    Cancel = 67,
    Add = 65,
    Clear = 82,
}

An order event or order book operation.

For example usage see:

• Order actions
• Order tracking

Variants

Modify = 77

An existing order was modified: price and/or size.

Trade = 84

An aggressing order traded. Does not affect the book.

Fill = 70

An existing order was filled. Does not affect the book.

Cancel = 67

An order was fully or partially cancelled.

Add = 65

A new order was added to the book.

Clear = 82

Reset the book; clear all orders for an instrument.

Trait Implementations

impl AsRef<str> for Action

fn as_ref(&self) -> &str

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

impl Clone for Action

fn clone(&self) -> Action

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Action

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

Formats the value using the given formatter.

impl From<Action> for char

fn from(action: Action) -> Self

Converts to this type from the input type.

impl From<Action> for u8

fn from(enum_value: Action) -> Self

Converts to this type from the input type.

impl Hash for Action

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 Action

type Iterator = ActionIter

fn iter() -> ActionIter

impl IntoPy<Py<PyAny>> for Action

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

Performs the conversion.

impl PartialEq for Action

fn eq(&self, other: &Action) -> 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 Action

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for Action

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<Action>

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

Available on non-crate feature gil-refs only.

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