Implementations

impl PriceAccount

pub fn get_publish_time(&self) -> UnixTimestamp

pub fn get_price_no_older_than(
    &self,
    clock: &Clock,
    slot_threshold: u64
) -> Option<Price>

Get the last valid price as long as it was updated within slot_threshold slots of the current slot.

pub fn to_price_feed(&self, price_key: &Pubkey) -> PriceFeed

Trait Implementations

impl Clone for PriceAccount

fn clone(&self) -> PriceAccount

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PriceAccount

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

Formats the value using the given formatter.

impl Default for PriceAccount

fn default() -> PriceAccount

Returns the “default value” for a type.

impl PartialEq<PriceAccount> for PriceAccount

fn eq(&self, other: &PriceAccount) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Zeroable for PriceAccount

fn zeroed() -> Self

Calls zeroed.

impl Copy for PriceAccount

impl Eq for PriceAccount

impl Pod for PriceAccount

impl StructuralEq for PriceAccount

impl StructuralPartialEq for PriceAccount
