}

Whether to sell an exact input amount or buy an exact output amount.

Used in every order and quote request to specify the trade direction. Serialises to "sell" or "buy" in JSON.

let kind = OrderKind::Sell;
assert_eq!(kind.as_str(), "sell");
assert!(kind.is_sell());

Returns

"sell" for Sell, "buy" for Buy.

pub const fn is_sell(self) -> bool

Returns true if this is a sell order.

use cow_types::OrderKind;

assert!(OrderKind::Sell.is_sell());
assert!(!OrderKind::Buy.is_sell());

pub const fn is_buy(self) -> bool

Returns true if this is a buy order.

use cow_types::OrderKind;

assert!(OrderKind::Buy.is_buy());
assert!(!OrderKind::Sell.is_buy());

Trait Implementations

impl Clone for OrderKind

fn clone(&self) -> OrderKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OrderKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for OrderKind

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for OrderKind

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

Formats the value using the given formatter.

impl PartialEq for OrderKind

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&str> for OrderKind

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

Parse a CoW Protocol order kind from its API string.

Accepts "sell" or "buy".

type Error = CowError

The type returned in the event of a conversion error.
