hyperdb-compile-check

Internal crate — compile-time SQL validation logic for hyperdb-api.

This is a regular library (not a proc-macro crate) so its validation logic can be unit-tested with standard cargo test. The proc-macro shells in hyperdb-api-derive call into this crate when the compile-time feature is enabled.

Not intended for direct use. Enable via hyperdb-api-derive's compile-time cargo feature.
