Implementations§

Source §

impl ShardedTreeSnapshot

Source

pub fn encode(&self) -> Result<Vec<u8>, TreeError>

Encode a deterministic, versioned binary snapshot.

Field elements use canonical 32-byte big-endian encoding. Chain identity, block hash and sync cursor intentionally remain storage-layer metadata, so this blob can be embedded in any caller’s checkpoint format.

Source

pub fn decode(bytes: &[u8]) -> Result<Self, TreeError>
