Struct ethabi::Function

pub struct Function {
    pub name: String,
    pub inputs: Vec<Param>,
    pub outputs: Vec<Param>,
    pub constant: Option<bool>,
    pub state_mutability: StateMutability,
}

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<Bytes>

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>>

Parses the ABI function output to list of tokens.

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

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

Formats the value using the given formatter.

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

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

Deserialize this value from the given Serde deserializer.

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: &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::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.
