Struct Interface

pub struct Interface { /* private fields */ }

Available on crate feature contract only.

A smart contract interface.

Implementations

impl Interface

pub fn new(abi: JsonAbi) -> Interface

Creates a new contract interface from the provided ABI.

pub fn encode_input( &self, name: &str, args: &[DynSolValue], ) -> Result<Vec<u8>, Error>

Returns the ABI encoded data (including the selector) for the provided function and arguments.

Note

If the function exists multiple times and you want to use one of the overloaded versions, consider using Self::encode_input_with_selector.

pub fn encode_input_with_selector( &self, selector: &FixedBytes<4>, args: &[DynSolValue], ) -> Result<Vec<u8>, Error>

Returns the ABI encoded data (including the selector) for the function with the provided selector and arguments.

pub fn decode_input( &self, name: &str, data: &[u8], validate: bool, ) -> Result<Vec<DynSolValue>, Error>

ABI-decodes the given data according to the function’s types.

Note

If the function exists multiple times and you want to use one of the overloaded versions, consider using Self::decode_input_with_selector.

pub fn decode_input_with_selector( &self, selector: &FixedBytes<4>, data: &[u8], validate: bool, ) -> Result<Vec<DynSolValue>, Error>

Decode the provided ABI encoded bytes as the input of the provided function selector.

pub fn decode_output( &self, name: &str, data: &[u8], validate: bool, ) -> Result<Vec<DynSolValue>, Error>

Decode the provided ABI encoded bytes as the output of the first function with the given name.

Note

If there are multiple functions with the same name, consider using Self::decode_output_with_selector

pub fn decode_output_with_selector( &self, selector: &FixedBytes<4>, data: &[u8], validate: bool, ) -> Result<Vec<DynSolValue>, Error>

Decode the provided ABI encoded bytes as the output of the provided function selector.

pub const fn abi(&self) -> &JsonAbi

Returns a reference to the contract’s ABI.

pub fn into_abi(self) -> JsonAbi

Consumes the interface, returning the inner ABI.

pub const fn connect<T, P, N>( self, address: Address, provider: P, ) -> ContractInstance<T, P, N>

Create a ContractInstance from this ABI for a contract at the given address.

Trait Implementations

impl Clone for Interface

fn clone(&self) -> Interface

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Interface

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

Formats the value using the given formatter.
