Struct Function 

pub struct Function {
    pub name: String,
    pub inputs: Vec<Param>,
    pub outputs: Vec<Param>,
}

A function as Solidity or viem writes it: transfer(address to, uint256 amount) returns (bool), with or without function and its modifiers.

Fields

name: String

inputs: Vec<Param>

outputs: Vec<Param>

Implementations

impl Function

pub fn parse(text: &str) -> Result<Function, AbiError>

pub fn signature(&self) -> String

name(t1,t2), what the selector hashes.

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

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

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

The calldata of a call: the selector, then the arguments.

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

A call’s arguments back out of its calldata.

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

What the call answered, read against its declared outputs.

Trait Implementations

impl Clone for Function

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Function

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

Formats the value using the given formatter.

impl Eq for Function

impl PartialEq for Function

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

Equality operator ==.

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

Inequality operator !=.
