Implementations

impl Function

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

This is supported on feature="abi" only.

Prepares ABI function call with given input params.

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

This is supported on feature="abi" only.

Parses the ABI function output to list of tokens.

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

This is supported on feature="abi" only.

Parses the ABI function input to a list of tokens.

pub fn signature(&self) -> String

This is supported on feature="abi" only.

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

This is supported on feature="abi" only.

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

fn selector(&self) -> Selector

This is supported on feature="abi" only.

Compute the Keccak256 function selector used by contract ABIs.

impl PartialEq<Function> 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: &Function) -> bool

This method tests for !=.

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.
