impl Clone for PgPageRankStore

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PageRankStore for PgPageRankStore

fn rank_of<'life0, 'life1, 'async_trait>( &'life0 self, iri: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<f64>, DomainError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

The stored PageRank score for one object IRI, or None when the IRI carries no score. The combine step reads a missing score as 1.0, SBOLExplorer’s unknown-part convention.

fn ranks_for<'life0, 'life1, 'async_trait>( &'life0 self, iris: &'life1 [String], ) -> Pin<Box<dyn Future<Output = Result<HashMap<String, f64>, DomainError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

The stored scores for a set of IRIs, keyed by IRI. IRIs with no stored score are absent from the map rather than defaulted, so the caller can tell “unranked” from a real score.

fn all_ranks<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<RankRow>, DomainError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Every stored (iri, score) pair, feeding a full text-index rebuild.

fn replace_all_ranks<'life0, 'async_trait>( &'life0 self, ranks: Vec<RankRow>, ) -> Pin<Box<dyn Future<Output = Result<(), DomainError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Replace the entire rank table with ranks in one transaction: after it returns the table reflects exactly this write and nothing prior.
