Struct LevelNode 

pub struct LevelNode {
    pub id: [u8; 32],
    pub hash: [u8; 32],
    pub parent_id: Option<[u8; 32]>,
    pub leaf_data: Option<TreeLeafData>,
}

A node in the level-wise traversal.

Contains enough information to compare with local state and decide whether to recurse or fetch leaf data.

Fields

id: [u8; 32]

Node ID.

hash: [u8; 32]

Merkle hash of this node.

parent_id: Option<[u8; 32]>

Parent node ID (None for root children).

leaf_data: Option<TreeLeafData>

Leaf data (present only for leaf nodes). Includes full data and metadata for CRDT merge.

Implementations

impl LevelNode

pub fn internal( id: [u8; 32], hash: [u8; 32], parent_id: Option<[u8; 32]>, ) -> Self

Create an internal node.

pub fn leaf( id: [u8; 32], hash: [u8; 32], parent_id: Option<[u8; 32]>, data: TreeLeafData, ) -> Self

Create a leaf node.

pub fn is_leaf(&self) -> bool

Check if this is a leaf node.

pub fn is_internal(&self) -> bool

Check if this is an internal node.

pub fn is_valid(&self) -> bool

Check if node is within valid bounds.

Call this after deserializing from untrusted sources.

Trait Implementations

impl BorshDeserialize for LevelNode

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for LevelNode

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for LevelNode

fn clone(&self) -> LevelNode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LevelNode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for LevelNode

fn eq(&self, other: &LevelNode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
