Oracle feed interface description

Required Methods

fn base(env: Env) -> Asset

Return the base asset the price is reported in

fn assets(env: Env) -> Vec<Asset>

Return all assets quoted by the price feed

fn decimals(env: Env) -> u32

Return the number of decimals for all assets quoted by the oracle

fn resolution(env: Env) -> u32

Return default tick period timeframe (in seconds)

fn price(env: Env, asset: Asset, timestamp: u64) -> Option<PriceData>

Get price in base asset at specific timestamp

fn prices(env: Env, asset: Asset, records: u32) -> Option<Vec<PriceData>>

Get last N price records

fn lastprice(env: Env, asset: Asset) -> Option<PriceData>

Get the most recent price for an asset

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
