Implementations§

source§

impl Function

source

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

Prepares ABI function call with given input params.

source

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

Return the 4 byte short signature of this function.

source

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

Parses the ABI function output to list of tokens.

source

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

Parses the ABI function input to a list of tokens.

source

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)

impl FunctionExt for Function

source§

impl PartialEq for Function

source§

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

1.0.0 · source§

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.
