[−][src]Enum sp_runtime::generic::ChangesTrieSignal

pub enum ChangesTrieSignal {
    NewConfiguration(Option<ChangesTrieConfiguration>),
}

Available changes trie signals.

Variants

NewConfiguration(Option<ChangesTrieConfiguration>)

New changes trie configuration is enacted, starting from next block.

The block that emits this signal will contain changes trie (CT) that covers blocks range [BEGIN; current block], where BEGIN is (order matters):

LAST_TOP_LEVEL_DIGEST_BLOCK+1 if top level digest CT has ever been created using current configuration AND the last top level digest CT has been created at block LAST_TOP_LEVEL_DIGEST_BLOCK;
LAST_CONFIGURATION_CHANGE_BLOCK+1 if there has been CT configuration change before and the last configuration change happened at block LAST_CONFIGURATION_CHANGE_BLOCK;
1 otherwise.
