Eth filters rpc api (polling).

Required Methods

fn new_filter(&self, _: Filter) -> Result<U256>

Returns id of new filter.

fn new_block_filter(&self) -> Result<U256>

Returns id of new block filter.

fn new_pending_transaction_filter(&self) -> Result<U256>

Returns id of new block filter.

fn filter_changes(&self, _: Index) -> Result<FilterChanges>

Returns filter changes since last poll.

fn filter_logs(&self, _: Index) -> Result<Vec<Log>>

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

fn uninstall_filter(&self, _: Index) -> Result<bool>

Uninstalls filter.

Provided Methods

fn to_delegate<M: Metadata>(self) -> IoDelegate<Self, M>

Create an IoDelegate, wiring rpc calls to the trait methods.

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.
