Enum HashTree

pub enum HashTree<'a> {
    Empty,
    Fork(Box<(HashTree<'a>, HashTree<'a>)>),
    Labeled(&'a [u8], Box<HashTree<'a>>),
    Leaf(Cow<'a, [u8]>),
    Pruned(Hash),
}

HashTree as defined in the interfaces spec.

Variants

Empty

No child nodes; a proof of absence.

Fork(Box<(HashTree<'a>, HashTree<'a>)>)

Left and right child branches.

Labeled(&'a [u8], Box<HashTree<'a>>)

A labeled child node.

Leaf(Cow<'a, [u8]>)

A leaf node containing a value or hash.

Pruned(Hash)

A branch that has been removed from this view of the tree, but is not necessarily absent.

Implementations

impl HashTree<'_>

pub fn reconstruct(&self) -> Hash
