Struct era_test_node::filters::EthFilters

pub struct EthFilters { /* private fields */ }

Keeps track of installed filters and their respective updates.

Implementations

impl EthFilters

pub fn add_block_filter(&mut self) -> Result<U256, &'static str>

Adds a block filter to keep track of new block hashes. Returns the filter id.

pub fn add_log_filter( &mut self, from_block: BlockNumber, to_block: BlockNumber, addresses: Vec<H160>, topics: [Option<HashSet<H256>>; 4] ) -> Result<U256, &'static str>

Adds a log filter to keep track of new transaction logs. Returns the filter id.

pub fn add_pending_transaction_filter(&mut self) -> Result<U256, &'static str>

Adds a filter to keep track of new pending transaction hashes. Returns the filter id.

pub fn remove_filter(&mut self, id: U256) -> bool

Removes the filter with the given id. Returns true if the filter existed, false otherwise.

pub fn get_new_changes( &mut self, id: U256 ) -> Result<FilterChanges, &'static str>

Retrieves the filter updates with the given id. The updates are reset after this call.

pub fn get_filter(&self, id: U256) -> Option<&FilterType>

pub fn notify_new_block(&mut self, hash: H256)

Notify available filters of a newly produced block

pub fn notify_new_pending_transaction(&mut self, hash: H256)

Notify available filters of a new pending transaction

pub fn notify_new_log(&mut self, log: &Log, latest_block_number: U64)

Notify available filters of a new transaction log

Trait Implementations

impl Clone for EthFilters

fn clone(&self) -> EthFilters

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EthFilters

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for EthFilters

fn default() -> EthFilters

Returns the “default value” for a type.

impl PartialEq<EthFilters> for EthFilters

fn eq(&self, other: &EthFilters) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
