Trait for executing and importing the block.

Required Methods

fn execution_strategy(&self) -> BlockExecutionStrategy

Returns the type of block execution strategy used.

fn execute_block( &self, parent_hash: Block::Hash, block: Block, ) -> Result<ExecuteBlockResult<Block>>

Executes the given block on top of the state specified by the parent hash.

fn import_block<'life0, 'async_trait>( &'life0 mut self, import_params: BlockImportParams<Block>, ) -> Pin<Box<dyn Future<Output = Result<ImportResult, Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Imports the block using the given import params.

Provided Methods

fn is_in_memory_backend_used(&self) -> bool

Determines whether the block should be imported in the executor.

import_block only makes sense for the executor using in memory backend.
