Struct ProofNodes

pub struct ProofNodes(/* private fields */);

A wrapper struct for trie node key to RLP encoded trie node.

Implementations

impl ProofNodes

pub fn matching_nodes_iter<'a>( &'a self, target: &'a Nibbles, ) -> impl Iterator<Item = (&'a Nibbles, &'a Bytes)>

Return iterator over proof nodes that match the target.

pub fn matching_nodes(&self, target: &Nibbles) -> Vec<(Nibbles, Bytes)>

Return the vec of proof nodes that match the target.

pub fn matching_nodes_sorted(&self, target: &Nibbles) -> Vec<(Nibbles, Bytes)>

Return the sorted vec of proof nodes that match the target.

pub fn insert(&mut self, key: Nibbles, node: Bytes) -> Option<Bytes>

Insert the RLP encoded trie node at key.

pub fn nodes_sorted(&self) -> Vec<(Nibbles, Bytes)>

Return the sorted vec of all proof nodes.

pub fn into_nodes_sorted(self) -> Vec<(Nibbles, Bytes)>

Convert into sorted vec of all proof nodes.

pub fn into_inner(self) -> HashMap<Nibbles, Bytes>

Convert wrapper struct into inner map.

pub fn extend_from(&mut self, other: Self)

Extends with the elements of another ProofNodes.

Trait Implementations

impl Clone for ProofNodes

fn clone(&self) -> ProofNodes

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ProofNodes

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

Formats the value using the given formatter.

impl Default for ProofNodes

fn default() -> ProofNodes

Returns the “default value” for a type.

impl Deref for ProofNodes

type Target = HashMap<Nibbles, Bytes>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Extend<(Nibbles, Bytes)> for ProofNodes

fn extend<T: IntoIterator<Item = (Nibbles, Bytes)>>(&mut self, iter: T)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

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

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

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

Reserves capacity in a collection for the given number of additional elements.

impl FromIterator<(Nibbles, Bytes)> for ProofNodes

fn from_iter<T: IntoIterator<Item = (Nibbles, Bytes)>>(iter: T) -> Self

Creates a value from an iterator.

impl PartialEq for ProofNodes

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