Struct ReplicationSnapshot 

pub struct ReplicationSnapshot { /* private fields */ }

A consistent database-directory image plus the leader commit epoch it covers. The image is opaque to HTTP; encode/decode use the core’s versioned bincode envelope so server and client share one format.

Implementations

impl ReplicationSnapshot

pub fn epoch(&self) -> u64

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

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

pub fn install(&self, destination: impl AsRef<Path>) -> Result<()>

Atomically replace destination with this snapshot and mark it as a read-only replica. Files are first written and fsynced in a sibling staging directory; an existing destination is retained until install.
