Core of the [`somnia`](https://crates.io/crates/somnia) SurrealDB ORM: the
type-safe query builder, expression tree, and the `SurrealRecord` / `SurrealSchema`
traits.
Most users should depend on the umbrella [`somnia`](https://crates.io/crates/somnia)
crate instead, which re-exports everything here plus the derive macro, client, and
migrator.
