Struct DecodedProofRetainer

pub struct DecodedProofRetainer { /* private fields */ }

Proof retainer is used to store proofs during merkle trie construction. It is intended to be used within the HashBuilder.

Implementations

impl DecodedProofRetainer

pub fn new(targets: Vec<Nibbles>) -> Self

Create new retainer with target nibbles.

pub fn matches(&self, prefix: &Nibbles) -> bool

Returns true if the given prefix matches the retainer target.

pub fn into_proof_nodes(self) -> DecodedProofNodes

Returns all collected proofs.

pub fn retain(&mut self, prefix: &Nibbles, proof: &[u8]) -> Result<(), Error>

Retain the proof if the key matches any of the targets.

Returns an error if the proof could not be decoded from the given proof bytes.
