Enum sp_storage::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.

Variants§

§

V0

Old state version, no value nodes.

§

V1

New state version can use value nodes.

Implementations§

source §

impl StateVersion

source

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.
