Required Associated Constants

const NAME: &'static str

Required Methods

fn match_call(log: &Call) -> bool

fn decode(log: &Call) -> Result<Self, String>

fn encode(&self) -> Vec<u8>

Provided Methods

fn match_and_decode(call: impl AsRef<Call>) -> Option<Self>

Attempts to match and decode the call. If Self::match_call(log) is false, returns None. If it matches, but decoding fails, logs the decoding error and returns None.
