BranchNodeMasks

reth_trie

Struct BranchNodeMasks 

pub struct BranchNodeMasks {
    pub hash_mask: TrieMask,
    pub tree_mask: TrieMask,
}
Expand description

Branch node masks containing hash_mask and tree_mask.

Consolidates hash_mask and tree_mask into a single struct, reducing HashMap overhead when storing masks by path. Instead of two separate HashMap<Nibbles, TrieMask>, we use a single HashMap<Nibbles, BranchNodeMasks>.

Fields§

§hash_mask: TrieMask

Hash mask indicating which children are stored as hashes.

§tree_mask: TrieMask

Tree mask indicating which children are complete subtrees.

Implementations§

§

impl BranchNodeMasks

pub fn from_optional( hash_mask: Option<TrieMask>, tree_mask: Option<TrieMask>, ) -> Option<BranchNodeMasks>

Creates masks from optional hash and tree masks.

Returns None if both masks are None, otherwise defaults missing masks to empty.
