CatalogManifestStore

laminar_core::cluster::control::catalog_manifest

Struct CatalogManifestStore 

Source 
pub struct CatalogManifestStore { /* private fields */ }
Expand description

Catalog view over the same append-only authority used for leader fencing.

Implementations§

Source§

impl CatalogManifestStore

Source

pub fn new(authority: Arc<LeaderLeaseStore>) -> Self

Share the exact append-only authority used by the leader lease manager.

Source

pub async fn load( &self, ) -> Result<Option<CatalogManifest>, CatalogManifestError>

Load the sealed catalog, or None before the first successful seal.

§Errors

Fails on object-store I/O, malformed JSON, or an invalid inventory.

Source

pub async fn seal( &self, manifest: &CatalogManifest, proof: &LeaderProof, ) -> Result<CatalogSealOutcome, CatalogManifestError>

CAS-append the first inventory under an exact leader proof.

A concurrent exact inventory is idempotent. Any different winner fails closed.

§Errors

Fails for an invalid proposal, divergent winner, or object-store I/O.
