pub struct SqlitePaperTagRepository { /* private fields */ }

Implementations

impl SqlitePaperTagRepository

pub fn new(db: Database) -> Self

pub fn record( &self, paper_id: &str, tag: &str, source: &str, ) -> Result<bool, DbError>

Record a tag. Idempotent on (paper_id, tag) — re-running an import that already added the tag is a no-op. Returns true if a new row was inserted, false if it already existed.

pub fn record_in_tx( tx: &Transaction<'_>, paper_id: &str, tag: &str, source: &str, ) -> Result<bool, DbError>

Transactional sibling of Self::record (#157). Used by the bib-import orchestrator so paper-save + alias / annotation / tag writes commit (or roll back) as a single unit per row.

pub fn list_for(&self, paper_id: &str) -> Result<Vec<(String, String)>, DbError>

All tags for a paper, in insertion order. Returned as (tag, source) so callers can distinguish bibtex-import- originated tags from manually-added ones.

pub fn tags_for(&self, paper_id: &str) -> Result<Vec<String>, DbError>

Tag names only, in insertion order. Convenience for the export path which only needs the strings (no source metadata).

pub fn lookup_all(&self, tag: &str) -> Result<Vec<String>, DbError>

All paper IDs carrying a tag, in deterministic order. Mirrors SqlitePaperAliasRepository::lookup_all so a future “filter by tag” UI can pick this up without a new method.

Trait Implementations

impl Clone for SqlitePaperTagRepository

fn clone(&self) -> SqlitePaperTagRepository

Returns a duplicate of the value.

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

Performs copy-assignment from source.
