Trait SolEnum

pub trait SolEnum:
    Sized
    + Copy
    + Into<u8>
    + TryFrom<u8, Error = Error> {
    const COUNT: usize;

    // Provided methods
    fn tokenize(self) -> WordToken { ... }
    fn abi_decode(data: &[u8], validate: bool) -> Result<Self> { ... }
    fn abi_encode_raw(self, out: &mut Vec<u8>) { ... }
    fn abi_encode(self) -> Vec<u8>  { ... }
}

A Solidity enum. This is always a wrapper around a u8.

Implementer’s Guide

It should not be necessary to implement this trait manually. Instead, use the sol! procedural macro to parse Solidity syntax into types that implement this trait.

Required Associated Constants

const COUNT: usize

The number of variants in the enum.

This is generally between 1 and 256 inclusive.

Provided Methods

fn tokenize(self) -> WordToken

Tokenize the enum.

fn abi_decode(data: &[u8], validate: bool) -> Result<Self>

ABI decode the enum from the given buffer.

fn abi_encode_raw(self, out: &mut Vec<u8>)

ABI encode the enum into the given buffer.

fn abi_encode(self) -> Vec<u8>

ABI encode the enum.

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.
