Struct Method 

pub struct Method {
    pub signature: &'static str,
    pub returns: &'static str,
}

A function: its canonical name(types) and what it answers.

Fields

signature: &'static str

name(t1,t2), as the selector hashes it.

returns: &'static str

What it answers, as a parameter list: uint64 gasEstimate, uint64 gasEstimateForL1.

Implementations

impl Method

pub const fn new(signature: &'static str, returns: &'static str) -> Method

pub fn selector(&self) -> [u8; 4]

The four bytes that name it: the start of keccak256(signature).

pub fn calldata(&self, args: &[Arg<'_>]) -> Vec<u8>

The calldata of a call: the selector, then the arguments, encoded as abi.encode lays them out. The arguments are the function’s, in order.

pub fn answer(&self, data: &[u8]) -> Result<Vec<Token>, AbiError>

The answer read against Method::returns.
