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

Returns true if the given prefix matches the retainer target.

pub fn into_proof_nodes(self) -> ProofNodes

Returns all collected proofs.

pub fn retain(&mut self, prefix: &Nibbles, proof: &[u8])

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