Crate hydracache_sqlx 

SQLx-facing integration crate for HydraCache database result caching.

The database-neutral query cache API lives in hydracache-db. This crate keeps SQLx users on a convenient import path while avoiding a hard conceptual dependency between the generic adapter and SQLx itself.

Example

use hydracache::HydraCache;
use hydracache_sqlx::{DbCache, SqlxQueryExt};

let local = HydraCache::local().build();

// SQLx users may import DbCache from this crate, but the type itself is
// database-neutral and comes from hydracache-db.
let queries = DbCache::new(local, "db");

let (id, name): (i64, String) = queries
    .cached::<(i64, String)>()
    .key("user:42")
    .tag("user:42")
    .fetch_one(
        pool.clone(),
        sqlx::query_as("select id, name from users where id = $1").bind(42_i64),
    )
    .await?;

assert_eq!(id, 42);
assert!(!name.is_empty());

Use DbQuery::fetch_with when you need SQLx macros, transactions, or a repository function instead of a pool-like executor.
