Derive Macro AbiCoder

#[derive(AbiCoder)]

Macro to include support for structures and enums in Solidity.

Overview

This macro is used to include support for structures and enums in Solidity. This allows them to encode and decode in \ from the Solidity Abi format, as well as create their views into Solidity lang.

Implemented trais

• AbiType
• AbiRead
• AbiWrite
• SolidityTypeName
• SolidityStructTy - for struct
• SolidityEnumTy - for enum

Limitations

• All struct fields must implement traits listed above.
• Enum must have u8 layout.
• Enum must implement folowing traits: Default, Copy, Clone

Example

use evm_coder::AbiCoder;

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

#[derive(AbiCoder, Default, Clone, Copy)]
#[repr(u8)]
enum Color {
    Red,
    Green,
    #[default]
    Blue,
}
