Expand description

Contract function specification.

Fields

name: String

Function name.

inputs: Vec<Param, Global>

Function input.

outputs: Vec<Param, Global>

Function output.

constant: Option<bool>

👎 Deprecated:

The constant attribute was removed in Solidity 0.5.0 and has been replaced with stateMutability.

Constant function.

state_mutability: StateMutability

Whether the function reads or modifies blockchain state

Implementations

source

impl Function

source

pub fn encode_input(&self, tokens: &[Token ]) -> Result<Vec<u8, Global>, Error>

Prepares ABI function call with given input params.

source

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