pub struct OpBuilder<'a, Txs> { /* private fields */ }
Expand description
The type that builds the payload.
Payload building for optimism is composed of several steps. The first steps are mandatory and defined by the protocol.
- first all System calls are applied.
- After canyon the forced deployed
create2deployer
must be loaded - all sequencer transactions are executed (part of the payload attributes)
Depending on whether the node acts as a sequencer and is allowed to include additional
transactions (no_tx_pool == false
):
4. include additional transactions
And finally 5. build the block: compute all roots (txs, state)

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
