Struct frame_executive::Executive

source · [−]

pub struct Executive<System, Block, Context, UnsignedValidator, AllModules, OnRuntimeUpgrade = ()>(_);

Expand description

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.
AllModules: Tuple that contains all modules. Will be used to call e.g. on_initialize.
OnRuntimeUpgrade: Custom logic that should be called after a runtime upgrade. Modules are already called by AllModules. It will be called before all modules will be called.

Implementations

impl<System: Config, Block: Block<Header = System::Header, Hash = System::Hash>, Context: Default, UnsignedValidator, AllModules: OnRuntimeUpgrade + OnInitialize<System::BlockNumber> + OnFinalize<System::BlockNumber> + OffchainWorker<System::BlockNumber>, COnRuntimeUpgrade: OnRuntimeUpgrade> Executive<System, Block, Context, UnsignedValidator, AllModules, COnRuntimeUpgrade> where
    Block::Extrinsic: Checkable<Context> + Codec,
    CheckedOf<Block::Extrinsic, Context>: Applyable + GetDispatchInfo,
    CallOf<Block::Extrinsic, Context>: Dispatchable<Info = DispatchInfo, PostInfo = PostDispatchInfo>,
    OriginOf<Block::Extrinsic, Context>: From<Option<System::AccountId>>,
    UnsignedValidator: ValidateUnsigned<Call = CallOf<Block::Extrinsic, Context>>,

pub fn initialize_block(header: &System::Header)

Start the execution of a particular block.

pub fn execute_block(block: Block)

Actually execute all transitions for block.

pub fn finalize_block() -> System::Header

Finalize the block - it is up the caller to ensure that all header fields are valid except state-root.

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
) -> 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.

pub fn offchain_worker(header: &System::Header)

Start an offchain worker and generate extrinsics.
