Enum Extended

pub enum Extended<BuiltIn, Other> {
    BuiltIn(BuiltIn),
    Other(Other),
}

An enum that combines two different transaction types.

This is intended to be used to extend existing presets, for example the ethereum or optstack transaction types and receipts

Note: The Extended::Other variants must not overlap with the builtin one, transaction types must be unique. For example if Extended::BuiltIn contains an EIP-1559 type variant, Extended::Other must not include that type.

Variants

BuiltIn(BuiltIn)

The builtin transaction type.

Other(Other)

The other transaction type.
