Functions

func Copy

func Copy(dst, src any) error

Copy shallow copies the value src to dst. If src is an anonymous struct or an array/slice of anonymous structs, the fields of the anonymous struct are copied to dst.

Types

type Arguments

type Arguments []abi.Argument

Arguments represents a slice of abi.Argument's.

func Parse

func Parse(s string) (a Arguments, err error)

Parse parses the given Solidity args and returns its arguments.

func ParseWithName

func ParseWithName(s string) (name string, a Arguments, err error)

ParseWithName parses the given Solidity function/event signature and returns its name and arguments.

func (Arguments) Decode

func (a Arguments) Decode(data []byte, args ...any) error

Decode ABI-decodes the given data to the given arguments args.

func (Arguments) Encode

func (a Arguments) Encode(args ...any) ([]byte, error)

Encode ABI-encodes the given arguments args.

func (Arguments) EncodeWithSelector

func (a Arguments) EncodeWithSelector(selector [4]byte, args ...any) ([]byte, error)

EncodeWithSelector ABI-encodes the given arguments args prepended by the given selector.

func (Arguments) EncodeWithSignature

func (a Arguments) EncodeWithSignature(signature string, args ...any) ([]byte, error)

EncodeWithSignature ABI-encodes the given arguments args prepended by the first 4 bytes of the hash of the given signature.

func (Arguments) Signature

func (a Arguments) Signature() string

func (Arguments) SignatureWithName

func (a Arguments) SignatureWithName(name string) string
