Enum sp_runtime::StateVersion
source · pub enum StateVersion {
V0,
V1,
}
Expand description
Different possible state version.
V0 and V1 uses a same trie implementation, but V1 will write external value node in the trie for
value with size at least TRIE_VALUE_NODE_THRESHOLD
.

impl StateVersion
sourcepub fn state_value_threshold(&self) -> Option<u32>
pub fn state_value_threshold(&self) -> Option<u32>
If defined, values in state of size bigger or equal to this threshold will use a separate trie node. Otherwhise, value will be inlined in branch or leaf node.
