Required Methods

fn quote( dex_id: DEXId, input_asset_id: &AssetId, output_asset_id: &AssetId, amount: QuoteAmount<Balance>, filter: LiquiditySourceFilter<DEXId, LiquiditySourceType>, deduce_fee: bool ) -> Result<SwapOutcome<Balance>, DispatchError>

Get spot price of tokens based on desired amount, None returned if liquidity source does not have available exchange methods for indicated path.

fn exchange( dex_id: DEXId, sender: &AccountId, receiver: &AccountId, input_asset_id: &AssetId, output_asset_id: &AssetId, amount: SwapAmount<Balance>, filter: LiquiditySourceFilter<DEXId, LiquiditySourceType> ) -> Result<SwapOutcome<Balance>, DispatchError>

Perform exchange based on desired amount.
