Enum PriceQuality 

pub enum PriceQuality {
    Fast,
    Optimal,
    Verified,
}

Quote price-quality hint passed to the orderbook.

Controls the trade-off between response speed and price accuracy when requesting a quote via POST /api/v1/quote.

Example

use cow_types::PriceQuality;

let quality = PriceQuality::Optimal;
assert_eq!(quality.as_str(), "optimal");
assert!(quality.is_optimal());

Variants

Fast

Fast estimate — may be slightly stale.

Optimal

Optimal price — runs the full solver pipeline.

Verified

Like optimal but includes on-chain simulation to verify executability.

Implementations

impl PriceQuality

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

Returns the lowercase string used by the CoW Protocol API.

Returns

"fast", "optimal", or "verified".

pub const fn is_fast(self) -> bool

Returns true if the fast (potentially stale) price quality is selected.

pub const fn is_optimal(self) -> bool

Returns true if the optimal (full solver pipeline) price quality is selected. This is the default.

pub const fn is_verified(self) -> bool

Returns true if the verified (on-chain simulation) price quality is selected.

Trait Implementations

impl Clone for PriceQuality

fn clone(&self) -> PriceQuality

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PriceQuality

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

Formats the value using the given formatter.

impl Default for PriceQuality

fn default() -> PriceQuality

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PriceQuality

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PriceQuality

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

Formats the value using the given formatter.

impl PartialEq for PriceQuality

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

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 PriceQuality

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

Parse a CoW Protocol price quality hint from its API string.

Accepts "fast", "optimal", or "verified".

type Error = CowError

The type returned in the event of a conversion error.
