Struct ProofSerializer 

pub struct ProofSerializer {
    pub stats: ProofSerializerStats,
}

Serializes and deserializes distributed proof trees.

The serializer is stateless apart from its ProofSerializerStats counter set; it can therefore be shared freely across threads via an Arc.

Fields

stats: ProofSerializerStats

Cumulative operation counters.

Implementations

impl ProofSerializer

pub fn new() -> Self

Creates a new ProofSerializer with zeroed counters.

pub fn serialize( &self, input: &ProofTreeInput, ) -> Result<SerializedProof, ProofSerError>

Flattens input into a SerializedProof using DFS pre-order traversal.

Errors

• ProofSerError::EmptyTree when nodes is empty.
• ProofSerError::MissingNode when the root or any child ID is absent.
• ProofSerError::CycleDetected when the tree contains a cycle.

pub fn deserialize( &self, proof: &SerializedProof, ) -> Result<ProofTreeInput, ProofSerError>

Reconstructs a ProofTreeInput from a SerializedProof.

Errors

Returns ProofSerError::EmptyTree when the proof contains no nodes, or ProofSerError::MissingNode when a referenced child is absent.

pub fn to_json(&self, proof: &SerializedProof) -> Result<String, ProofSerError>

Encodes proof as a compact JSON string.

pub fn from_json(&self, json: &str) -> Result<SerializedProof, ProofSerError>

Decodes a SerializedProof from a JSON string.

Trait Implementations

impl Debug for ProofSerializer

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

Formats the value using the given formatter.

impl Default for ProofSerializer

fn default() -> ProofSerializer

Returns the “default value” for a type.
