Crate narwhal_drivers 

Bundled database drivers for narwhal.

Each engine (postgres, mysql, sqlite, duckdb, clickhouse, mssql) lives behind a cargo feature of the same name. Enabling the all-drivers umbrella turns them all on; the narwhaldb binary relies on this. Library consumers pick what they need:

narwhal-drivers = { version = "1", default-features = false, features = ["postgres", "sqlite"] }

The crate also re-exports registry::DriverRegistry as DriverRegistry, which replaces the v1.x narwhal-driver-registry crate.

Re-exports

pub use registry::DriverRegistry;

Modules

registry

Driver registry shared by every host that needs to address a narwhal_core::DatabaseDriver by name (the TUI app, the MCP server, the headless CLI). Concrete driver implementations are pulled in by cargo features so a build can ship only the engines it needs.

Functions

registry

Convenience constructor for a registry preloaded with every driver compiled into this build. Equivalent to DriverRegistry::with_defaults; kept as a free function so the historical narwhal_drivers::Registry::new() call shape has a minimally-disruptive migration target.
