// Package abi implements the Ethereum ABI (Application Binary// Interface).//// The Ethereum ABI is strongly typed, known at compile time// and static. This ABI will handle basic type casting; unsigned// to signed and visa versa. It does not handle slice casting such// as unsigned slice to signed slice. Bit size type casting is also// handled. ints with a bit size of 32 will be properly cast to int256,// etc.packageabi
