---

type

type: 0 = BinaryNodeType.Internal

Defined in: node/internalNode.ts:12

Methods

raw()

raw(): Uint8Array<ArrayBufferLike>[]

Defined in: node/internalNode.ts:101

Returns the raw serialized representation of this internal node as an array of Uint8Arrays.

The returned array contains:

1. A single-byte Uint8Array indicating the node type (BinaryNodeType.Internal).
2. For each child (left then right):
   • The child’s hash, or an empty Uint8Array if the child is null.
3. For each child (left then right):
   • An RLP-encoded tuple [pathLength, packedPathBytes] where:
     • pathLength is a one-byte Uint8Array representing the number of meaningful bits in the child’s path.
     • packedPathBytes is the packed byte representation of the child’s bit path (as produced by bitsToBytes).

Returns

Uint8Array<ArrayBufferLike>[]

Raw RLP array: type byte, child hashes, then RLP-encoded child paths
