Implementations

impl Filter

pub fn new() -> Self

pub fn from_block<T: Into<BlockNumber>>(self, block: T) -> Self

pub fn to_block<T: Into<BlockNumber>>(self, block: T) -> Self

pub fn address<T: Into<Address>>(self, address: T) -> Self

pub fn address_str(self, address: &str) -> Result<Self, FromHexError>

pub fn event(self, event_name: &str) -> Self

given the event in string form, it hashes it and adds it to the topics to monitor

pub fn topic0<T: Into<ValueOrArray<H256>>>(self, topic: T) -> Self

Sets topic0 (the event name for non-anonymous events)

pub fn topic1<T: Into<ValueOrArray<H256>>>(self, topic: T) -> Self

Sets the 1st indexed topic

pub fn topic2<T: Into<ValueOrArray<H256>>>(self, topic: T) -> Self

Sets the 2nd indexed topic

pub fn topic3<T: Into<ValueOrArray<H256>>>(self, topic: T) -> Self

Sets the 3rd indexed topic

pub fn limit(self, limit: usize) -> Self

Trait Implementations

impl Clone for Filter

fn clone(&self) -> Filter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Filter

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

Formats the value using the given formatter.

impl Default for Filter

fn default() -> Filter

Returns the "default value" for a type.

impl PartialEq<Filter> for Filter

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

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

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

This method tests for !=.
