Contract ABI
Implements encoding of parameters according to the Ethereum Contract ABI Specification.
Installation
Use the Nimble package manager to add contractabi
to an existing project.
Add the following to its .nimble file:
requires "https://github.com/status-im/nim-contract-abi >= 0.1.0 & < 0.2.0"
Usage
import contractabi
import stint
# encode unsigned integers, booleans, enums
AbiEncoder.encode(42'u8)
# encode uint256
AbiEncoder.encode(42.u256)
# encode byte arrays and sequences
AbiEncoder.encode([1'u8, 2'u8, 3'u8])
AbiEncoder.encode(@[1'u8, 2'u8, 3'u8])
# encode tuples
var encoder = AbiEncoder.init()
encoder.startTuple()
encoder.write(42'u8)
encoder.write(@[1'u8, 2'u8, 3'u8])
encoder.write(true)
encoder.finishTuple()
encoder.finish()
