Enum EvmVersion 

#[non_exhaustive]
pub enum EvmVersion {
    Homestead,
    TangerineWhistle,
    SpuriousDragon,

    Istanbul,
    Berlin,
    London,

    Prague,
    Osaka,
}

A version specifier of the EVM we want to compile to.

Defaults to the latest version deployed on Ethereum Mainnet at the time of compiler release.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
