Struct SqliteIouEnvelopeStore 

pub struct SqliteIouEnvelopeStore { /* private fields */ }

SQLite-backed IouEnvelopeStore implementation. Wraps an existing connection pool from crate::SqliteReceiptStore so IOU writes share the same SQLite database and journal mode.

Implementations

impl SqliteIouEnvelopeStore

pub fn open_with_pool( pool: Pool<SqliteConnectionManager>, ) -> Result<Self, IouEnvelopeStoreError>

Open a store backed by the same pool as a sibling receipt store. Runs the additive migration if the table is absent.

pub fn open_alongside( store: &SqliteReceiptStore, ) -> Result<Self, IouEnvelopeStoreError>

Construct the store sharing the connection pool of an existing crate::SqliteReceiptStore. The receipt store has already configured WAL / synchronous=FULL on every connection out of the pool, so no additional connection setup is needed. Writes are routed through the receipt store’s writer handle so they serialize with receipt commits on the single writer connection; reads keep using the reader pool.

Trait Implementations

impl IouEnvelopeStore for SqliteIouEnvelopeStore

fn insert(&self, envelope: &IouEnvelope) -> Result<bool, IouEnvelopeStoreError>

Persist envelope. Returns Ok(true) when the envelope was inserted, or Ok(false) when an identical envelope already exists. Returns IouEnvelopeStoreError::Conflict when a different envelope is recorded for the same receipt_id.

fn get_by_receipt_id( &self, receipt_id: &str, ) -> Result<Option<IouEnvelope>, IouEnvelopeStoreError>

Fetch the IOU envelope previously persisted for receipt_id, or Ok(None) when no envelope is recorded.
