Enum Side 

#[repr(u8)]
pub enum Side {
    Long = 0,
    Short = 1,
}

Re-export of core financial types from the standalone financial_types crate.

This module re-exports fundamental trading enums (Action, Side, OptionStyle, UnderlyingAssetType) and option contract type definitions (OptionType, sub-enums, OptionBasicType) from their respective external crates. Defines the directional exposure of a financial position.

Indicates whether a trader expects to profit from rising prices (Long) or falling prices (Short). This is a fundamental concept in trading that determines how profits and losses are calculated and affects risk management considerations.

Examples

use financial_types::Side;

let side = Side::Long;
assert!(side.is_long());
assert!(!side.is_short());
assert_eq!(format!("{side}"), "Long");

Variants

Long = 0

Profits when the underlying asset’s price increases. Long positions involve buying an asset with the expectation of selling at a higher price.

Short = 1

Profits when the underlying asset’s price decreases. Short positions involve selling an asset (often borrowed) with the expectation of buying it back at a lower price.

Implementations

impl Side

pub const fn is_long(&self) -> bool

Returns true if this is a Long position.

pub const fn is_short(&self) -> bool

Returns true if this is a Short position.

pub const fn opposite(&self) -> Side

Returns the opposite side.

• Long → Short
• Short → Long

Trait Implementations

impl Clone for Side

fn clone(&self) -> Side

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Side

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

Formats the value using the given formatter.

impl Default for Side

fn default() -> Side

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Side

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Side

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

Formats the value using the given formatter.

impl Hash for Side

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 PartialEq for Side

fn eq(&self, other: &Side) -> 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 Serialize for Side

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 ToSchema for Side

fn name() -> Cow<'static, str>

Return name of the schema.

fn schemas(schemas: &mut Vec<(String, RefOr<Schema>)>)

Implement reference utoipa::openapi::schema::Schemas for this type.

impl Copy for Side

impl Eq for Side

impl StructuralPartialEq for Side
