Fields

id: Identifier

Unique identifier for this price.

status: PriceStatus

Status of price (Trading is valid).

publish_time: i64

Current price aggregation publish time

expo: i32

Price exponent.

max_num_publishers: u32

Maximum number of allowed publishers that can contribute to a price.

num_publishers: u32

Number of publishers that made up current aggregate.

product_id: Identifier

Product account key.

Implementations

impl PriceFeed

pub fn new( id: Identifier, status: PriceStatus, publish_time: i64, expo: i32, max_num_publishers: u32, num_publishers: u32, product_id: Identifier, price: i64, conf: u64, ema_price: i64, ema_conf: u64, prev_price: i64, prev_conf: u64, prev_publish_time: i64, ) -> PriceFeed

Constructs a new Price Feed

pub fn get_current_price(&self) -> Option<Price>

Get the current price and confidence interval as fixed-point numbers of the form a * 10^e.

Returns a struct containing the current price, confidence interval, and the exponent for both numbers. Returns None if price information is currently unavailable for any reason.

pub fn get_current_price_unchecked(&self) -> Price

Get the “unchecked” current price and confidence interval as fixed-point numbers of the form a * 10^e.

Returns a struct containing the current price, confidence interval, and the exponent for both numbers. This method returns the price value without checking availability of the price. This value might not be valid or updated when the price is not available. Please use get_current_price where possible.

pub fn get_ema_price(&self) -> Option<Price>

Get the exponential moving average price (ema_price) and a confidence interval on the result.

Returns None if the ema price is currently unavailable. At the moment, the confidence interval returned by this method is computed in a somewhat questionable way, so we do not recommend using it for high-value applications.

pub fn get_ema_price_unchecked(&self) -> Price

Get the “unchecked” exponential moving average price (ema_price) and a confidence interval on the result.

Returns the price value without checking availability of the price. This value might not be valid or updated when the price is not available. Please use get_ema_price where possible.

At the moment, the confidence interval returned by this method is computed in a somewhat questionable way, so we do not recommend using it for high-value applications.

pub fn get_prev_price_unchecked(&self) -> (Price, i64)

Get the “unchecked” previous price with Trading status, along with the timestamp at which it was generated.

WARNING: We make no guarantees about the unchecked price and confidence returned by this function: it could differ significantly from the current price. We strongly encourage you to use get_current_price instead.

Trait Implementations

impl BorshDeserialize for PriceFeed

where Identifier: BorshDeserialize, PriceStatus: BorshDeserialize, i64: BorshDeserialize, i32: BorshDeserialize, u32: BorshDeserialize, u64: BorshDeserialize,

fn deserialize(buf: &mut &[u8]) -> Result<PriceFeed, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

impl BorshSerialize for PriceFeed

where Identifier: BorshSerialize, PriceStatus: BorshSerialize, i64: BorshSerialize, i32: BorshSerialize, u32: BorshSerialize, u64: BorshSerialize,

fn serialize<W>(&self, writer: &mut W) -> Result<(), Error>

where W: Write,

fn try_to_vec(&self) -> Result<Vec<u8>, Error>

Serialize this instance into a vector of bytes.

impl Clone for PriceFeed

fn clone(&self) -> PriceFeed

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PriceFeed

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

Formats the value using the given formatter.

impl Default for PriceFeed

fn default() -> PriceFeed

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PriceFeed

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for PriceFeed

fn schema_name() -> String

The name of the generated JSON Schema.

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

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for PriceFeed

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

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.
