pub fn log0<D>(self, data: D) -> Self

where D: Into<Vec<u8>>,

pub fn log1<D, T0>(self, topic0: T0, data: D) -> Self

where D: Into<Vec<u8>>, T0: Into<H256>,

Add a 1-topic log.

pub fn log2<D, T0, T1>(self, topic0: T0, topic1: T1, data: D) -> Self

where D: Into<Vec<u8>>, T0: Into<H256>, T1: Into<H256>,

Add a 2-topics log.

pub fn log3<D, T0, T1, T2>( self, topic0: T0, topic1: T1, topic2: T2, data: D, ) -> Self

where D: Into<Vec<u8>>, T0: Into<H256>, T1: Into<H256>, T2: Into<H256>,

Add a 3-topics log.

pub fn log4<D, T0, T1, T2, T3>( self, topic0: T0, topic1: T1, topic2: T2, topic3: T3, data: D, ) -> Self

where D: Into<Vec<u8>>, T0: Into<H256>, T1: Into<H256>, T2: Into<H256>, T3: Into<H256>,
