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.

Legacy

Header layout before EIP-1559.

London

Header layout with base_fee_per_gas.

Shanghai

Header layout with withdrawals_root.

Cancun

Header layout with blob gas fields and parent_beacon_block_root.

Prague
