Contract function specification.

Fields

name: String

Function name.

inputs: Vec<Param>

Function input.

outputs: Vec<Param>

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

impl Function

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

Prepares ABI function call with given input params.

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

Return the 4 byte short signature of this function.

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

Parses the ABI function output to list of tokens.

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

Parses the ABI function input to a list of tokens.

pub fn signature(&self) -> String

Returns a signature that uniquely identifies this function.

Examples:

• functionName()
• functionName():(uint256)
• functionName(bool):(uint256,string)
• functionName(uint256,bytes32):(string,uint256)

Trait Implementations

impl Clone for Function

fn clone(&self) -> Function

Returns a copy 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<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Function

fn deserialize<__D>( __deserializer: __D ) -> Result<Function, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FunctionExt for Function

fn abi_signature(&self) -> String

Compute the method signature in the standard ABI format. This does not include the output types.

fn selector(&self) -> Selector

Compute the Keccak256 function selector used by contract ABIs.

impl PartialEq for Function

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Function

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
