Trait AbiType

pub trait AbiType {
    const SIGNATURE: SignatureUnit;
    const IS_DYNAMIC: bool;
    const HEAD_WORDS: u32;

    // Provided method
    fn signature() -> &'static str { ... }
}

Helper for type.

Required Associated Constants

const SIGNATURE: SignatureUnit

Signature for Ethereum ABI.

const IS_DYNAMIC: bool

Is this a dynamic type, per spec.

const HEAD_WORDS: u32

How many AbiWords static data this type should occupy

Provided Methods

fn signature() -> &'static str

Signature as str.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
