Struct RootBuilder 

pub struct RootBuilder<'h, H: PartHasher> { /* private fields */ }

Computes a part’s root from its leaves in order, keeping one hash per complete subtree, so a streamed part never holds its leaves.

Implementations

impl<'h, H: PartHasher> RootBuilder<'h, H>

pub fn new(hasher: &'h H) -> Self

Start an empty part.

pub fn push(&mut self, leaf: &Leaf) -> Result<[u8; 32], Error>

Add the next leaf, returning its keyed hash.

pub fn finish(self) -> [u8; 32]

The root over every leaf pushed.
