Enum Direction 

#[repr(i32)]
pub enum Direction {
    Long = 0,
    Short = 1,
}

Trade direction used by strategies.

Variants

Long = 0

Long position / buy direction.

Short = 1

Short position / sell direction.

Implementations

impl Direction

pub fn quantity(&self, quantity: f64) -> f64

Convert direction to a signed quantity.

pub fn from_quantity(quantity: f64) -> Direction

Determine direction from a signed quantity.

Panics

Panics if quantity is zero or NaN.

pub fn opposite(&self) -> Direction

Return the opposite direction.

pub fn value(&self) -> f64

Return 1.0 for long, -1.0 for short.

Trait Implementations

impl Clone for Direction

fn clone(&self) -> Direction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Direction

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Direction

fn deserialize<__D>( __deserializer: __D, ) -> Result<Direction, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Direction

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 Ord for Direction

fn cmp(&self, other: &Direction) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Direction

fn eq(&self, other: &Direction) -> 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 PartialOrd for Direction

fn partial_cmp(&self, other: &Direction) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Direction

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<i32> for Direction

type Error = TryFromPrimitiveError<Direction>

The type returned in the event of a conversion error.

fn try_from(number: i32) -> Result<Direction, TryFromPrimitiveError<Direction>>

Performs the conversion.

impl TryFromPrimitive for Direction

const NAME: &'static str = "Direction"

type Primitive = i32

type Error = TryFromPrimitiveError<Direction>

fn try_from_primitive( number: <Direction as TryFromPrimitive>::Primitive, ) -> Result<Direction, TryFromPrimitiveError<Direction>>
