Struct pallet_executive::Executive

pub struct Executive<System, Block, Context, UnsignedValidator, AllPalletsWithSystem, OnRuntimeUpgrade = ()>(/* private fields */);

Main entry point for certain runtime actions as e.g. execute_block.

Generic parameters:

• System: Something that implements frame_system::Config
• Block: The block type of the runtime
• Context: The context that is used when checking an extrinsic.
• UnsignedValidator: The unsigned transaction validator of the runtime.
• AllPalletsWithSystem: Tuple that contains all pallets including frame system pallet. Will be used to call hooks e.g. on_initialize.
• OnRuntimeUpgrade: Custom logic that should be called after a runtime upgrade. Modules are already called by AllPalletsWithSystem. It will be called before all modules will be called.

pub fn initialize_block(header: &HeaderFor<System>) -> ExtrinsicInclusionMode

Start the execution of a particular block.

pub fn execute_block(block: Block)

Actually execute all transitions for block.

pub fn execute_block_without_state_root_check(block: Block)

Actually execute all transitions for block.

pub fn finalize_block_without_checks(header: HeaderFor<System>)

pub fn inherents_applied()

Logic that runs directly after inherent application.

It advances the Multi-Block-Migrations or runs the on_poll hook.

pub fn apply_extrinsic(uxt: Block::Extrinsic) -> ApplyExtrinsicResult

Apply extrinsic outside of the block execution function.

This doesn’t attempt to validate anything regarding the block, but it builds a list of uxt hashes.

pub fn validate_transaction( source: TransactionSource, uxt: Block::Extrinsic, block_hash: Block::Hash, ) -> TransactionValidity

Check a given signed transaction for validity. This doesn’t execute any side-effects; it merely checks whether the transaction would panic if it were included or not.

Changes made to storage should be discarded.
