Trait representing type configuring a chain spec.

Required Associated Types

type Header

The header type of the network.

Required Methods

fn chain(&self) -> Chain

Returns the Chain object this spec targets.

fn base_fee_params_at_block(&self, block_number: u64) -> BaseFeeParams

Get the BaseFeeParams for the chain at the given block.

fn base_fee_params_at_timestamp(&self, timestamp: u64) -> BaseFeeParams

Get the BaseFeeParams for the chain at the given timestamp.

fn deposit_contract(&self) -> Option<&DepositContract>

Returns the deposit contract data for the chain, if it’s present

fn genesis_hash(&self) -> FixedBytes<32>

The genesis hash.

fn prune_delete_limit(&self) -> usize

The delete limit for pruner, per run.

fn display_hardforks(&self) -> Box<dyn Display>

Returns a string representation of the hardforks.

fn genesis_header(&self) -> &Self::Header

The genesis header.

fn genesis(&self) -> &Genesis

The genesis block specification.

fn bootnodes(&self) -> Option<Vec<NodeRecord>>

The bootnodes for the chain, if any.

Provided Methods

fn chain_id(&self) -> u64

Returns the chain id number

fn is_optimism(&self) -> bool

Returns true if this chain contains Optimism configuration.

fn is_ethereum(&self) -> bool

Returns true if this chain contains Ethereum configuration.
