Server trait implementation for the EthFilterApi RPC API.

Required Methods

fn new_filter(&self, filter: Filter) -> Result<U256, ErrorObject<'static>>

Returns id of new filter.

fn new_block_filter(&self) -> Result<U256, ErrorObject<'static>>

Returns id of new block filter.

fn new_pending_transaction_filter(&self) -> Result<U256, ErrorObject<'static>>

Returns id of new block filter.

fn filter_changes<'life0, 'async_trait>( &'life0 self, index: Index, ) -> Pin<Box<dyn Future<Output = Result<FilterChanges, ErrorObject<'static>>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

Returns filter changes since last poll.

fn filter_logs<'life0, 'async_trait>( &'life0 self, index: Index, ) -> Pin<Box<dyn Future<Output = Result<Vec<Log>, ErrorObject<'static>>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

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

fn uninstall_filter(&self, index: Index) -> Result<bool, ErrorObject<'static>>

Uninstalls filter.

fn logs<'life0, 'async_trait>( &'life0 self, filter: Filter, ) -> Pin<Box<dyn Future<Output = Result<Vec<Log>, ErrorObject<'static>>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

Returns logs matching given filter object.

Provided Methods

fn into_rpc(self) -> RpcModule<Self>

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", so this trait is not object safe.
