Implementations

impl ReplicationState

pub fn load(state_dir: &Path) -> OsmicResult<Self>

Load replication state from a state directory.

pub fn save(&self, state_dir: &Path) -> OsmicResult<()>

Save replication state to a state directory.

pub fn next_osc_url(&self) -> String

OSM replication files use a 9-digit sequence number split into 3-digit directory segments: 000/001/234.osc.gz

pub fn init(base_url: &str, sequence_number: u64) -> Self

Create initial state for a given base URL and sequence number.
