Struct MptProof 

pub struct MptProof { /* private fields */ }

A Merkle Patricia Trie proof for a single key.

Contains an ordered sequence of encoded nodes from the root to the key’s position. For membership proofs value is Some(v). For non-membership proofs value is None.

Fields are crate-private to prevent external mutation; use the accessor methods to read them.

Implementations

impl MptProof

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

Returns the key this proof covers.

pub fn value(&self) -> Option<&[u8]>

Returns Some(value) for membership proofs, None for non-membership proofs.

pub fn nodes(&self) -> &[Vec<u8>]

Returns the encoded proof nodes from root to the key’s position.

Trait Implementations

impl Clone for MptProof

fn clone(&self) -> MptProof

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MptProof

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

Formats the value using the given formatter.

impl PartialEq for MptProof

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