Provided Methods§

source

fn all_positions( &self ) -> Pin<Box<dyn Stream<Item = Result<Position>> + Send + 'static>>

Return a stream of all [position::Metadata] available.

source

fn positions_by_price( &self, pair: &DirectedTradingPair ) -> Pin<Box<dyn Stream<Item = Result<Id>> + Send + 'static>>

Returns a stream of position::Id ordered by effective price.

source

fn position_by_id<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 Id ) -> Pin<Box<dyn Future<Output = Result<Option<Position>>> + Send + 'async_trait>>
where Self: Sync + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

source

fn check_position_by_id<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 Id ) -> Pin<Box<dyn Future<Output = Result<bool>> + Send + 'async_trait>>
where Self: Sync + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

source

fn best_position<'life0, 'life1, 'async_trait>( &'life0 self, pair: &'life1 DirectedTradingPair ) -> Pin<Box<dyn Future<Output = Result<Option<Position>>> + Send + 'async_trait>>
where Self: Sync + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

source

fn pending_position_closures(&self) -> Vector<Id>

Fetch the list of pending position closures.

source

fn candidate_set( &self, from: Id, fixed_candidates: Arc<Vec<Id>> ) -> Pin<Box<dyn Stream<Item = Result<Id>> + Send>>

Returns the list of candidate assets to route through for a trade from from. Combines a list of fixed candidates with a list of liquidity-based candidates. This ensures that the fixed candidates are always considered, minimizing the risk of attacks on routing.

source

fn ordered_routable_assets( &self, start: &Id ) -> Pin<Box<dyn Stream<Item = Result<Id>> + Send + 'static>>

Returns a stream of asset::Id routable from a given asset, ordered by liquidity.

source

fn recently_accessed_assets(&self) -> OrdSet<Id>

Fetch the list of assets interacted with during this block.
