linera-alloy-sol-types

Compile-time representation of Ethereum's type system with ABI and EIP-712 support.

This crate provides a developer-friendly interface to Ethereum's type system, by representing Solidity types. See type_system.md for a rundown, and the crate docs for more information

Features

• static representation of Solidity types
• ABI encoding and decoding
• EIP-712 encoding and decoding
• EIP-712 Domain object w/ serde support

Usage

See the crate docs for more details.

// Declare a solidity type in standard solidity
sol! {
    struct Foo {
        bar: u256;
        baz: bool;
    }
}

// A corresponding Rust struct is generated!
let foo = Foo {
    bar: 42.into(),
    baz: true,
};

// Works for UDTs
sol! { type MyType is uint8; }
let my_type = MyType::from(42u8);

// For errors
sol! {
    error MyError(
        string message,
    );
}

// And for functions!
sol! { function myFunc() external returns (uint256); }
