Server trait implementation for the EthFilterApi RPC API.

Required Methods

fn new_filter( &self, filter: Filter, ) -> impl Future<Output = RpcResult<FilterId>> + Send

Creates a new filter and returns its id.

fn new_block_filter(&self) -> impl Future<Output = RpcResult<FilterId>> + Send

Creates a new block filter and returns its id.

fn new_pending_transaction_filter( &self, kind: Option<PendingTransactionFilterKind>, ) -> impl Future<Output = RpcResult<FilterId>> + Send

Creates a pending transaction filter and returns its id.

fn filter_changes( &self, id: FilterId, ) -> impl Future<Output = RpcResult<FilterChanges<T, L>>> + Send

Returns all filter changes since last poll.

fn filter_logs( &self, id: FilterId, ) -> impl Future<Output = RpcResult<Vec<L>>> + Send

Returns all logs matching given filter (in a range ‘from’ - ‘to’).

fn uninstall_filter( &self, id: FilterId, ) -> impl Future<Output = RpcResult<bool>> + Send

Uninstalls filter.

fn logs(&self, filter: Filter) -> impl Future<Output = RpcResult<Vec<L>>> + Send

Returns logs matching given filter object.

Provided Methods

fn into_rpc(self) -> RpcModule<Self>

where T: Send + Sync + 'static + Clone + Serialize, L: Send + Sync + 'static + Clone + Serialize,

Collects all the methods and subscriptions defined in the trait and adds them into a single RpcModule.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
