Struct exonum::storage::proof_map_index::ProofPath

pub struct ProofPath { /* fields omitted */ }

Bit slice type used internally to serialize ProofMapKeys.

A single slice can contain from 1 to PROOF_MAP_KEY_SIZE* 8 bits.

Binary representation

Position in bytes	Description
0	ProofPath kind: (0 is branch, 1 is leaf)
1..33	ProofMapKey bytes.
33	Total length in bits of ProofMapKey for branches.

JSON serialization

Serialized as a string of '0' and '1' chars, corresponding exactly to bits in the slice.

Methods

impl ProofPath

pub fn new<K: ProofMapKey>(key: &K) -> Self

Creates a path from the given key.

pub fn is_leaf(&self) -> bool

Checks if this is a path to a leaf ProofMapIndex node.

pub fn as_bytes(&self) -> &[u8]

Returns the byte representation of contained ProofMapKey.

Trait Implementations

impl StorageKey for ProofPath

fn size(&self) -> usize

Returns the size of the serialized key in bytes.

fn write(&self, buffer: &mut [u8])

Serializes the key into the specified buffer of bytes.

fn read(buffer: &[u8]) -> Self::Owned

Deserializes the key from the specified buffer of bytes.

impl PartialOrd<ProofPath> for ProofPath

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.

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

impl Copy for ProofPath

impl PartialEq<ProofPath> for ProofPath

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

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