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 AsRef<Node> for Node

fn as_ref(&self) -> &Self

Performs the conversion.

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 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 Eq for Node

impl From<NodeParts<Hash>> for Node

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

Performs the conversion.

impl Node for Node

fn index(&self) -> usize

Get the position at which the node was found.

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 Ord for Node

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

This method returns an [Ordering] between self and other.

#[must_use] fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use] fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use] fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Node> 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 PartialOrd<Node> for Node

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

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

#[must_use] fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use] fn le(&self, other: &Rhs) -> bool

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

#[must_use] fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use] fn ge(&self, other: &Rhs) -> bool

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