SqliteLfsRows

Struct SqliteLfsRows 

Source
pub struct SqliteLfsRows { /* private fields */ }
Expand description

The sqlite row twin over the co-tenant lfs_objects rows (substrate.md §refs’ row-store pattern, ADR-019 §2): every write call (LfsRows::assert, LfsRows::remove, LfsRows::remove_repo) runs its check-and-writes inside one BEGIN IMMEDIATE transaction on the co-tenant connection — two clashing calls (cross-connection included) serialize on the write lock and the refcount recompute reads the committed winner. The refcount recompute is the transaction’s trailing statement — the touched oid’s rows all carry the same current count at commit. Blocking SQL bridges off the async executor (tokio::task::spawn_blocking) per the composition’s concurrency model; construction takes the already-migrated (CoTenantSqlite::open) handle — no construction I/O here. The record-removal leg that takes a repo’s rows with the record rides the registry twin’s own in-SQL copy (crate::sqlite — unconditional, see the module doc); this impl’s LfsRows::remove_repo is the surface’s own leg for the same row set.

Implementations§

Source§

impl SqliteLfsRows

Source

pub fn new(handle: CoTenantSqlite) -> Self

Mount the row store over a co-tenant handle (the same handle the sqlite registry and refs twins consume).

Trait Implementations§

Source§

impl LfsRows for SqliteLfsRows

Source§

fn assert<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, repo_id: &'life1 str, oid: &'life2 str, size: u64, ) -> Pin<Box<dyn Future<Output = Result<(), StorageError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Assert a reference: insert the (repo_id, oid) row with the asserted size, or — when the pair already has a row — refresh that row’s size and change nothing else (the refcount-aware upsert: one oid re-asserted in one repo is one row).
Source§

fn remove<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, repo_id: &'life1 str, oid: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<(), StorageError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Remove one reference row. An absent row is a success no-op; the oid’s surviving rows recompute their refcount.
Source§

fn remove_repo<'life0, 'life1, 'async_trait>( &'life0 self, repo_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<(), StorageError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

The repo-deletion leg: the repo’s rows go with the repo (its oids’ surviving rows in other repos recompute their refcount).
Source§

fn rows<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<LfsRow>, StorageError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

The liveness read — all rows, canonical (repo_id, oid) order.
Source§

fn repo_rows<'life0, 'life1, 'async_trait>( &'life0 self, repo_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<LfsRow>, StorageError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

The liveness read — one repo’s rows, canonical oid order.
