Struct MastNodeFingerprint 

pub struct MastNodeFingerprint { /* private fields */ }

Represents the hash used to test for equality between MastNodes.

The decorator root will be None if and only if there are no decorators attached to the node, and all children have no decorator roots (meaning that there are no decorators in all the descendants).

Implementations

impl MastNodeFingerprint

Constructors

pub fn new(mast_root: Word) -> MastNodeFingerprint

Creates a new MastNodeFingerprint from the given MAST root with an empty decorator root.

pub fn with_decorator_root( mast_root: Word, decorator_root: Blake3Digest<32>, ) -> MastNodeFingerprint

Creates a new MastNodeFingerprint from the given MAST root and the given DecoratorFingerprint.

pub fn from_mast_node( forest: &MastForest, hash_by_node_id: &impl LookupByIdx<MastNodeId, MastNodeFingerprint>, node: &MastNode, ) -> Result<MastNodeFingerprint, MastForestError>

Creates a MastNodeFingerprint from a MastNode.

The hash_by_node_id map must contain all children of the node for efficient lookup of their fingerprints. This function returns an error if a child of the given node is not in this map.

Trait Implementations

impl Clone for MastNodeFingerprint

fn clone(&self) -> MastNodeFingerprint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MastNodeFingerprint

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

Formats the value using the given formatter.

impl Ord for MastNodeFingerprint

fn cmp(&self, other: &MastNodeFingerprint) -> 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 MastNodeFingerprint

fn eq(&self, other: &MastNodeFingerprint) -> 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 MastNodeFingerprint

fn partial_cmp(&self, other: &MastNodeFingerprint) -> 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.
