Struct BranchNodeV2 

pub struct BranchNodeV2 {
    pub key: Nibbles,
    pub stack: Vec<RlpNode>,
    pub state_mask: TrieMask,
    pub branch_rlp_node: Option<RlpNode>,
}
Expand description

A branch node in an Ethereum Merkle Patricia Trie.

Branch node is a 17-element array consisting of 16 slots that correspond to each hexadecimal character and an additional slot for a value. We do exclude the node value since all paths have a fixed size.

This node also encompasses the possible parent extension node of a branch via the key field.

Fields§

§key: Nibbles

The key for the branch’s parent extension. if key is empty then the branch does not have a parent extension.

§stack: Vec<RlpNode>

The collection of RLP encoded children.

§state_mask: TrieMask

The bitmask indicating the presence of children at the respective nibble positions

§branch_rlp_node: Option<RlpNode>

RlpNode encoding of the branch node. Always provided when key is not empty (i.e this is an extension node).

Implementations§

§

impl BranchNodeV2

pub const fn new( key: Nibbles, stack: Vec<RlpNode>, state_mask: TrieMask, branch_rlp_node: Option<RlpNode>, ) -> BranchNodeV2

Creates a new branch node with the given short key, stack, and state mask.
