Struct LevelWiseResponse 

pub struct LevelWiseResponse {
    pub level: usize,
    pub nodes: Vec<LevelNode>,
    pub has_more_levels: bool,
}

Response containing nodes at a specific level.

Fields

level: usize

Level these nodes are at.

nodes: Vec<LevelNode>

Nodes at this level.

Limited to MAX_NODES_PER_LEVEL entries. Use is_valid() to check bounds after deserialization from untrusted sources.

has_more_levels: bool

Whether there are more levels below this one.

Implementations

impl LevelWiseResponse

pub fn new(level: usize, nodes: Vec<LevelNode>, has_more_levels: bool) -> Self

Create a response with nodes.

pub fn empty(level: usize) -> Self

Create an empty response (no nodes at this level).

pub fn node_count(&self) -> usize

Number of nodes at this level.

pub fn is_empty(&self) -> bool

Check if this level is empty.

pub fn leaves(&self) -> impl Iterator<Item = &LevelNode>

Get an iterator over leaf nodes at this level.

pub fn internal_nodes(&self) -> impl Iterator<Item = &LevelNode>

Get an iterator over internal nodes at this level.

pub fn internal_node_ids(&self) -> Vec<[u8; 32]>

Get IDs of all internal nodes (for next level request).

pub fn is_valid(&self) -> bool

Check if response is within valid bounds.

Call this after deserializing from untrusted sources to prevent resource exhaustion attacks. Validates both response size and all contained nodes.

Trait Implementations

impl BorshDeserialize for LevelWiseResponse

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 LevelWiseResponse

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

impl Clone for LevelWiseResponse

fn clone(&self) -> LevelWiseResponse

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LevelWiseResponse

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

Formats the value using the given formatter.

impl PartialEq for LevelWiseResponse

fn eq(&self, other: &LevelWiseResponse) -> 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.
