Struct InMemoryRefTable 

pub struct InMemoryRefTable { /* private fields */ }

The in-memory refs table — the CAS-semantics reference impl (engine-free, single-process, stamp-free by construction: it builds fresh every time and versions nothing durable — ADR-024 §6). Rows are keyed on the resolved repo id (repo_id → name → row), name-sorted maps (deterministic listing); the whole call runs under one short-held write lock — the in-memory “transaction” — with the atomic abort as simply not committing the call’s working copy (per-update decisions inside still see their in-call predecessors). The lock is the async tokio::sync::RwLock: its guard is held across the (never-yielding) CAS futures’ awaits and is Send — the GitRefs Send-future surface holds (a blocking guard across an await would not).

Implementations

impl InMemoryRefTable

pub fn new() -> Self

A fresh, empty table.

Trait Implementations

impl Default for InMemoryRefTable

fn default() -> Self

Returns the “default value” for a type.

impl GitRefs for InMemoryRefTable

fn list_refs<'life0, 'life1, 'async_trait>( &'life0 self, repo: &'life1 RepoRecord, ) -> Pin<Box<dyn Future<Output = Result<Vec<RefLine>, StorageError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Ref listing — advertisement + ls-refs response data (the full set; ref-prefix filtering is wire-side, client-driven).

fn apply_updates<'life0, 'life1, 'async_trait>( &'life0 self, repo: &'life1 RepoRecord, updates: Vec<RefUpdate>, atomic: bool, ) -> Pin<Box<dyn Future<Output = Result<Vec<RefOutcome>, StorageError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

One CAS transaction per call — the atomic-correctness home (ADR-013 §7; the substrate row transaction — ADR-019 §2). Runs the per-ref CAS; per-ref denials are outcomes (RefOutcome), not errors (a stale ref is a business result of receive-pack — ADR-013 §7–8).

impl RefRows for InMemoryRefTable

fn snapshot<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<RefRowsSnapshot, StorageError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

The full canonical snapshot: all repos’ rows, name-sorted, with the fingerprint over the canonical form.
