Struct PriceRange 

pub struct PriceRange<Exp: Integer> {
    pub lower: UFix64<Exp>,
    pub upper: UFix64<Exp>,
}

Spread of an asset price, with a lower and upper quote. Use lower in minting, higher in redeeming.

Fields

lower: UFix64<Exp>

upper: UFix64<Exp>

Implementations

impl<Exp: Integer> PriceRange<Exp>

pub fn from_conf( price: UFix64<Exp>, conf: UFix64<Exp>, ) -> Result<PriceRange<Exp>>

Pyth does not publish a “true” price but a range of values defined by a base price and a confidence interval (μ-σ, μ+σ). This data type either returns the lower or upper bound of that range. See Pyth documentation

pub fn one(price: UFix64<Exp>) -> PriceRange<Exp>

Makes a range of one price, useful in test scenarios.

pub fn new(lower: UFix64<Exp>, upper: UFix64<Exp>) -> PriceRange<Exp>

Raw construction of range from lower and upper bounds.

Trait Implementations

impl<Exp: Clone + Integer> Clone for PriceRange<Exp>

fn clone(&self) -> PriceRange<Exp>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Exp: Debug + Integer> Debug for PriceRange<Exp>

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

Formats the value using the given formatter.

impl<Exp: PartialEq + Integer> PartialEq for PriceRange<Exp>

fn eq(&self, other: &PriceRange<Exp>) -> 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.
