Struct Node 

pub struct Node<E: NodeEntry = ChunkAddress> { /* private fields */ }

A node in the mantaray trie.

Implementations

impl<E: NodeEntry> Node<E>

pub fn new_unencrypted() -> Self

Create a new node with a zeroed obfuscation key (unencrypted).

pub fn from_reference(reference: ChunkAddress) -> Self

Create a node that references persisted data.

pub const fn entry(&self) -> Option<&E>

The typed entry stored at this node.

pub const fn metadata(&self) -> &BTreeMap<String, String>

Metadata key-value pairs attached to this node.

pub const fn reference(&self) -> Option<&ChunkAddress>

Content-addressed reference for this node.

pub const fn forks(&self) -> &BTreeMap<u8, Fork<E>>

Child forks keyed by the first byte of their prefix.

pub const fn obfuscation_key(&self) -> &ObfuscationKey

XOR obfuscation key for binary serialisation.

pub const fn is_value(&self) -> bool

Check if the node has a value (entry).

pub const fn is_edge(&self) -> bool

Check if the node has child forks.

pub const fn is_with_path_separator(&self) -> bool

Check if the path contains a separator.

pub const fn is_with_metadata(&self) -> bool

Check if the node has metadata.

Trait Implementations

impl<E: Clone + NodeEntry> Clone for Node<E>

fn clone(&self) -> Node<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug + NodeEntry> Debug for Node<E>

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

Formats the value using the given formatter.

impl<E: NodeEntry> Default for Node<E>

fn default() -> Self

Returns the “default value” for a type.

impl<E: Eq + NodeEntry> Eq for Node<E>

impl<E: PartialEq + NodeEntry> PartialEq for Node<E>

fn eq(&self, other: &Node<E>) -> 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<E: NodeEntry> StructuralPartialEq for Node<E>

impl<E: NodeEntry> TryFrom<&Node<E>> for Vec<u8>

type Error = MantarayError

The type returned in the event of a conversion error.

fn try_from(node: &Node<E>) -> Result<Self>

Performs the conversion.

impl<E: NodeEntry> TryFrom<&[u8]> for Node<E>

type Error = MantarayError

The type returned in the event of a conversion error.

fn try_from(value: &[u8]) -> Result<Self>

Performs the conversion.
