Struct hypercore::Node

pub struct Node { /* fields omitted */ }

Nodes that are persisted to disk.

Methods

impl Node

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

Create a new instance.

pub fn from_bytes(index: usize, buffer: &[u8]) -> Result<Self>

Convert a vector to a new instance.

Requires the index at which the buffer was read to be passed.

pub fn to_bytes(&self) -> Result<Vec<u8>>

Convert to a buffer that can be written to disk.

Trait Implementations

impl Debug for Node

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

Formats the value using the given formatter.

impl Clone for Node

fn clone(&self) -> Node

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for Node

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Eq for Node

impl NodeTrait for Node

fn index(&self) -> usize

Get the position at which the node was found.

Important traits for &'a [u8]

impl<'a> Read for &'a [u8]impl<'a> Write for &'a mut [u8]

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

Get the hash contained in the node.

fn len(&self) -> usize

Get the length of the node.

fn is_empty(&self) -> bool

Check if the length is zero.

fn parent(&self) -> usize

Get the position of the parent of the node.

impl AsRef<Node> for Node

Important traits for &'a mut R

impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

fn as_ref(&self) -> &Self

Performs the conversion.

impl Display for Node

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

Formats the value using the given formatter.
