holochain_data 0.7.0-dev.12

//! DHT database operations.
//!
//! Internally split into three layers:
//!
//! - `inner`: free-standing `async fn`s over `sqlx::Executor` per DHT
//!   table (one submodule per table).
//! - `db_operations`: thin `DbRead<Dht>` / `DbWrite<Dht>` method wrappers
//!   that acquire a pool executor and delegate into `inner`.
//! - `tx_operations`: thin `TxRead<Dht>` / `TxWrite<Dht>` method wrappers
//!   that delegate into `inner` using the in-flight transaction.
//!
//! Public API is exposed only via methods on the four handle types
//! ([`crate::DbRead`] / [`crate::DbWrite`] / [`crate::TxRead`] /
//! [`crate::TxWrite`]) plus the parameter structs re-exported here.
