Block import trait.

Associated Types

type Error: Error + Send + 'static

The error type.

type Transaction

The transaction type used by the backend.

Required methods

fn check_block(
    &mut self,
    block: BlockCheckParams<B>
) -> Result<ImportResult, Self::Error>

Check block preconditions.

fn import_block(
    &mut self,
    block: BlockImportParams<B, Self::Transaction>,
    cache: HashMap<CacheKeyId, Vec<u8>>
) -> Result<ImportResult, Self::Error>

Import a block.

Cached data can be accessed through the blockchain cache.
