// The crates whose types appear in this crate's public API are re-exported, so
// callers can reach them at a version that is guaranteed to match. Binding a
// `chrono::DateTime` or a `uuid::Uuid` only type-checks against the exact
// version `tdsql` was built with; a second copy in the dependency graph
// produces the notoriously opaque "expected `Uuid`, found `Uuid`" error.
//
// This follows Effective Rust item 24 ("re-export dependencies whose types
// appear in your API") and matches `sqlx::types`. The trade-off is real and
// deliberate: it couples `tdsql`'s major version to these three, so a breaking
// release of any of them forces one here. All three are mature and moving
// slowly, which is what makes that price acceptable.

/// The `chrono` version this crate binds against -- `tdsql::chrono::Utc`.
///
/// Its types appear in the public API as [`DataValue::Date`],
/// [`DataValue::Time`], [`DataValue::DateTime`] and
/// [`DataValue::DateTimeOffset`].

/// Its [`Uuid`](uuid::Uuid) is the public API's [`DataValue::Guid`], which is
