Enum trie_db::node::OwnedNode

source · [−]

pub enum OwnedNode {
    Empty,
    Leaf(NibbleVec, DBValue),
    Extension(NibbleVec, DBValue),

Expand description

An owning node type. Useful for trie iterators.

Variants

`Empty`

Empty trie node.

`Leaf(NibbleVec, DBValue)`

Leaf node: partial key and value.

`Extension(NibbleVec, DBValue)`

Extension node: partial key and child node.

`Branch(Branch)`

Branch node: 16 children and an optional value.
