TeaQL Rust reaches v0.7.0. The crates are published and documented.

Crate Structure​

teaql-core                   // Entity traits, metadata, and core queries
teaql-sql                    // SQL dialect and AST-to-SQL compiler
teaql-runtime                // UserContext, registry, graph writes, checkers, and events
teaql-macros                 // Derive macro for entity descriptors
teaql-provider-sqlx-postgres // PostgreSQL SQLx provider adapter
teaql-provider-sqlx-sqlite   // SQLite SQLx provider adapter
teaql-provider-sqlx-mysql    // MySQL SQLx provider adapter
teaql-provider-rusqlite      // synchronous SQLite rusqlite provider adapter

Each crate has a standalone readme with examples.

Aggregation Cache​

let cache = AggregationCache::new(CacheBackend::Memory)
    .namespace("daily_revenue")
    .ttl(Duration::from_secs(300));

let revenue: Decimal = cache
    .get_or_compute(|| compute_daily_revenue())
    .await?;

Namespaced caches prevent key collisions across different aggregations.

SQL Debug Logging​

let ctx = UserContext::new()
    .with_sql_debug(true);

// Logs: SELECT id, name FROM user_t WHERE age >= ?
// Params: [18]

Debug output shows the final SQL and bound parameters. Toggle per request via UserContext.

Extended Query Expressions​

let expr = User::age()
    .gte(18)
    .and(User::status().in_vec(&["active", "premium"]))
    .or(User::role().eq("admin"));

in_vec, between, like, and nested and/or groups are now supported.

v0.7.1 Patch​

Quick patch for documentation links. No functional changes.

What's Next​

Repository module split and open source cleanup.

DuckDB embedded analytical database integration, plus comprehensive request logging infrastructure.

DuckDB Integration​

+ teaql-duck: DuckDB repository implementation
+ Embedded analytical database support

DuckDB is ideal for OLAP analytical workloads.

Sub-View Support​

Views now support nested sub-views:

+ Sub-view fields in templates
+ Sub-view action candidates
+ Empty view customization per context
+ Go-to-view navigation

Request Logging and Tracing​

+ Request body caching for logging
+ Response header debug logging
+ Client IP tracking in UserContext
+ MDC trace headers (trace_id, span_id)
+ Response body logging

Toast Messages​

Toast/notification message support in the view rendering system.

UserContext Edit Hook​

// Modify requests before execution
ctx.beforeExecuteRequest(request -> {
    // Add default filters
    // Audit logging
    // Permission checks
});
