Required Associated Types

type Error: Error + Send + Sync

Required Methods

fn get( &self, id: ChainId, ) -> impl Future<Output = Result<Option<Chain>, Self::Error>> + Send

fn remove( &self, id: ChainId, ) -> impl Future<Output = Result<Option<Chain>, Self::Error>> + Send

fn items( &self, ) -> impl Stream<Item = Result<(ChainId, Chain), Self::Error>> + Send

fn insert( &self, id: ChainId, chain: Chain, ) -> impl Future<Output = Result<Option<Chain>, Self::Error>> + Send

fn try_insert( &self, id: ChainId, chain: Chain, ) -> impl Future<Output = Result<Option<Chain>, Self::Error>> + Send

fn modify( &self, id: ChainId, f: impl FnMut(&mut Chain) + Send, ) -> impl Future<Output = Result<Option<()>, Self::Error>> + Send

Modifies a chain in the wallet. Returns Ok(None) if the chain doesn’t exist.

Provided Methods

fn chain_ids(&self) -> impl Stream<Item = Result<ChainId, Self::Error>> + Send

fn owned_chain_ids( &self, ) -> impl Stream<Item = Result<ChainId, Self::Error>> + Send

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.
