[−][src]Struct exonum::blockchain::BlockchainBuilder
The object responsible for the correct Exonum blockchain creation from the components.
During the Blockchain creation it creates and commits a genesis block if the database
is empty. Otherwise, it restores the state from the database.
Methods
impl BlockchainBuilder[src]
pub fn new(blockchain: Blockchain) -> Self[src]
Creates a new builder instance based on the Blockchain.
pub fn with_genesis_config(self, genesis_config: GenesisConfig) -> Self[src]
Adds the genesis config to use if the blockchain is not yet initialized.
pub fn with_runtime(self, runtime: impl Into<RuntimeInstance>) -> Self[src]
Adds a runtime with the specified identifier and returns a modified Self object for
further chaining.
pub fn build(self) -> BlockchainMut[src]
Returns blockchain instance, creates and commits the genesis block with the specified genesis configuration if the blockchain has not been initialized. Otherwise restores dispatcher state from database.
Panics
- If the genesis config was not provided and the blockchain is not initialized.
- If the genesis block cannot be created.
- If storage version is not specified or not supported.
