Enum Action 

#[non_exhaustive]
#[repr(u8)]
pub enum Action {
    Buy = 0,
    Sell = 1,
    Other = 2,
}

Represents trading actions in a financial context.

Defines the fundamental trade operations that can be performed in a trading system. These actions represent the direction of a trade transaction.

Stability

This enum is #[non_exhaustive]. New trading actions may be added in minor releases without a major version bump. Downstream match expressions must include a wildcard arm (_ =>).

Examples

use financial_types::Action;

let action = Action::Buy;
assert!(action.is_buy());
assert_eq!(format!("{action}"), "Buy");

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Buy = 0

Represents a purchase transaction, where assets are acquired.

Sell = 1

Represents a selling transaction, where assets are disposed of.

Other = 2

Action is not applicable to this type of transaction.

Implementations

impl Action

pub const ALL: &'static [Self]

All variants in discriminant order.

pub const fn is_buy(&self) -> bool

Returns true if this is a Buy action.

pub const fn is_sell(&self) -> bool

Returns true if this is a Sell action.

pub const fn as_str(&self) -> &'static str

Returns the canonical string representation of this variant.

Matches the fmt::Display output exactly and is allocation-free.

pub const fn opposite(&self) -> Self

Returns the opposite trading action.

• Buy → Sell
• Sell → Buy
• Other → Other (no meaningful inverse)

Trait Implementations

impl Clone for Action

Returns a duplicate 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 Default for Action

fn default() -> Action

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Action

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Action

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

Formats the value using the given formatter.

impl FromStr for Action

type Err = ParseEnumError

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 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 Ord for Action

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

impl PartialEq for Action

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

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.

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<u8> for Action
