Module registry 

Table and struct registry for compile-time validation.

derive(Table) #[hyperdb(register)] calls into this registry at macro expansion time to record:

• The SQL CREATE TABLE statement for the table (for lazy seeding).
• The struct’s field-name list (for the name-subset diff in validate.rs).

Tables are seeded into the CompileTimeDb lazily: only when a query_as! dry-run returns SQLSTATE 42P01 (undefined_table) do we seed the relevant table and retry. This handles cross-file macro expansion ordering without requiring a client-side SQL parser.

Structs

Registry

The public Registry type — a thin newtype that provides the seeding interface against a live CompileTimeDb. Created from a lock guard by validate_query_as.

TableEntry

Information about a registered table derived from #[derive(Table)].

Functions

contains

Returns true if the SQL table name is known to the registry.

get_by_struct

Look up a registered entry by Rust struct ident. Returns (table_name, entry) so callers have the SQL name for seeding.

get_by_table

Look up a registered entry by SQL table name.

register

Register a table and its associated struct field list.

registered_names

All registered table names (for diagnostics).
