Enum sc_consensus::block_import::StateAction[−][src]

pub enum StateAction<Block: BlockT, Transaction> {
    ApplyChanges(StorageChanges<Block, Transaction>),

    Skip,
}

Expand description

Defines how a new state is computed for a given imported block.

Variants

ApplyChanges(StorageChanges<Block, Transaction>)

ExecuteIfPossible

Execute block body if parent state is available and compute state.

Skip

Don’t execute or import state.
