Struct DbPool

pub struct DbPool {
    pub zotero: Option<ZoteroDb>,
    pub bbt: Option<BbtDb>,
}

Holds connections to both Zotero databases.

Created once at startup and shared (by reference) across all tool calls. Both connections are read-only and held open for the process lifetime.

Fields

zotero: Option<ZoteroDb>

bbt: Option<BbtDb>

Implementations

impl DbPool

pub fn open(zotero_path: &Path, bbt_path: &Path) -> Self

Open both databases. Non-fatal: if a database doesn’t exist or can’t be opened, the corresponding field is None and tools that need it return a clear error.

pub fn empty() -> Self

Create an empty pool (for testing when no databases are available).

pub fn zotero(&self) -> Result<&ZoteroDb>

Get the Zotero database, returning a clear error if unavailable.

pub fn bbt(&self) -> Result<&BbtDb>

Get the BBT database, returning a clear error if unavailable.

pub fn item_key_for_citekey(&self, citekey: &str) -> Result<Option<String>>

Resolve a citekey to an item key, trying all available sources.

Priority:

1. zotero.sqlite citationKey field (most complete, 99.9% coverage)
2. better-bibtex.migrated (for items not yet synced to Zotero)

pub fn citekey_for_item_key(&self, item_key: &str) -> Option<String>

Resolve an item key to a citekey, trying all available sources.
