Struct OpHandler 

pub struct OpHandler<EVM, ERROR, FRAME> {
    pub mainnet: MainnetHandler<EVM, ERROR, FRAME>,
    pub _phantom: PhantomData<(EVM, ERROR, FRAME)>,
}

Available on crate feature evm only.

Optimism handler extends the Handler with Optimism specific logic.

Fields

mainnet: MainnetHandler<EVM, ERROR, FRAME>

Mainnet handler allows us to use functions from the mainnet handler inside optimism handler. So we dont duplicate the logic

_phantom: PhantomData<(EVM, ERROR, FRAME)>

Phantom data to avoid type inference issues.
