Struct Node 

pub struct Node { /* private fields */ }

Nodes of the Merkle Tree that are persisted to disk.

Implementations

impl Node

pub fn new(index: u64, hash: Vec<u8>, length: u64) -> Self

Create a new instance.

pub fn new_blank(index: u64) -> Self

Creates a new blank node

Trait Implementations

impl AsRef<Node> for Node

fn as_ref(&self) -> &Self

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Node

fn clone(&self) -> Node

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CompactEncoding for Node

fn encoded_size(&self) -> Result<usize, EncodingError>

The size in bytes required to encode self.

fn encode<'a>( &self, buffer: &'a mut [u8], ) -> Result<&'a mut [u8], EncodingError>

Encode self into buffer returning the remainder of buffer.

fn decode(buffer: &[u8]) -> Result<(Self, &[u8]), EncodingError>

where Self: Sized,

Decode a value from the given buffer of the type specified by the Decode type parameter (which defaults to Self). Returns the decoded value and remaining undecoded bytes.

fn to_encoded_bytes(&self) -> Result<Box<[u8]>, EncodingError>

Encode self into a Vec<u8>. This is just a helper method for creating a buffer and encoding to it in one step.

fn create_buffer(&self) -> Result<Box<[u8]>, EncodingError>

Create an empty buffer of the correct size for encoding self to. This is just a helper method for: encoding to it in one step.

fn encode_with_len<'a>( &self, buffer: &'a mut [u8], ) -> Result<(&'a mut [u8], usize), EncodingError>

Like CompactEncoding::encode but also return the number of bytes encoded.

fn decode_with_len( buffer: &[u8], ) -> Result<(Decode, &[u8], usize), EncodingError>

Like CompactEncoding::decode but also return the number of bytes decoded.

impl Debug for Node

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

Formats the value using the given formatter.

impl Display for Node

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

Formats the value using the given formatter.

impl From<NodeParts<Hash>> for Node

fn from(parts: NodeParts<Hash>) -> Self

Converts to this type from the input type.

impl Node for Node

fn index(&self) -> u64

Get the position at which the node was found.

fn hash(&self) -> &[u8]

Get the hash contained in the node.

fn len(&self) -> u64

Get the length of the node.

fn is_empty(&self) -> bool

Check if the length is zero.

fn parent(&self) -> u64

Get the position of the parent of the node.

impl Ord for Node

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Node

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

impl PartialOrd for Node

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl VecEncodable for Node

fn vec_encoded_size(vec: &[Self]) -> Result<usize, EncodingError>

where Self: Sized,

Calculate the resulting size in bytes of vec

fn vec_encode<'a>( vec: &[Self], buffer: &'a mut [u8], ) -> Result<&'a mut [u8], EncodingError>

where Self: Sized,

Encode vec to buffer

fn vec_decode(buffer: &[u8]) -> Result<(Vec<Self>, &[u8]), EncodingError>

where Self: Sized,

Decode Vec<Self> from buffer
