#[derive(AbiCoder)]
struct Struct {
	a: u8,
	b: String
}

#[derive(AbiCoder, Default, Clone, Copy)]
#[repr(u8)]
enum Enum {
	First,
	Second,
	#[default]
	Third,
}

使用AbiCoder派生的宏，维护你的类型变得如此简单。

最后，我们将指定sol文件的生成器。

generate_stubgen!(gen_impl, ContractHandleCall<()>, true);
generate_stubgen!(gen_iface, ContractHandleCall<()>, false);

scripts文件夹包含了一组用于生成接口、sol存根、json abi和编译合约的脚本。为此，创建以下make文件。

MyContract.sol:
	PACKAGE=package-name NAME=erc::gen_iface OUTPUT=/path/to/iface/$@ $(PATH_TO_SCRIPTS)/generate_sol.sh
	PACKAGE=package-name NAME=erc::gen_impl OUTPUT=/patch/to/stub/$@ $(PATH_TO_SCRIPTS)/generate_sol.sh

MyContract: MyContract.sol
	INPUT=/patch/to/stub/$< OUTPUT=/patch/to/compiled/contract/MyContract.raw ./.maintain/scripts/compile_stub.sh
	INPUT=/patch/to/stub/$< OUTPUT=/patch/to/abi ./.maintain/scripts/generate_abi.sh

结果，我们得到了以下sol接口文件。
