Struct GraphRepository 

pub struct GraphRepository { /* private fields */ }

Implementations

impl GraphRepository

pub fn new(pool: PgPool) -> Self

pub async fn insert( &self, conn: &mut PgConnection, id: GraphId, input: NewGraph, ) -> Result<GraphId, DomainError>

Create the sbol3-kind graph that backs a document. The caller mints the GraphId so the document’s triples can be attributed to its graph:document:{id} IRI before this write.

pub async fn exists_by_hash(&self, hash: &[u8]) -> Result<bool, DomainError>

Returns true when any document graph already carries this content hash. Used by bulk import to dedup re-uploaded files without re-parsing.

pub async fn get(&self, id: GraphId) -> Result<Option<GraphRecord>, DomainError>

pub async fn list( &self, filter: &ListGraphsFilter, ) -> Result<Vec<GraphRecord>, DomainError>

Paginated newest-first listing for the CLI / lab UI. Filters are optional and ANDed; cardinality is small so we don’t expose a keyset cursor here.

pub async fn delete(&self, id: GraphId) -> Result<bool, DomainError>

Delete one document by dropping its graph, which cascades to the graph’s triples. (Derived-view objects have an ON DELETE SET NULL FK and survive; cleaning them is the derived-view refresh’s job.) Returns true if a row was removed.

Trait Implementations

impl Clone for GraphRepository

fn clone(&self) -> GraphRepository

Returns a duplicate of the value.

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

Performs copy-assignment from source.
