vantage-surrealdb 0.5.9

/// Create a SurrealDB expression with automatic type conversion
///
/// Uses `expr_param!` from vantage-expressions for parameter handling:
/// - `surreal_expr!("template")` — no parameters
/// - `surreal_expr!("template", scalar)` — scalar becomes `ExpressiveEnum::Scalar(scalar.into())`
/// - `surreal_expr!("template", (expr))` — expr becomes `ExpressiveEnum::Nested(expr.expr())`
/// - `surreal_expr!("template", {deferred})` — deferred becomes `ExpressiveEnum::Deferred(deferred)`
///
/// Scalar arguments must implement `Into<AnySurrealType>` — supported types are:
/// `i8`–`u64`, `isize`/`usize`, `f32`/`f64`, `bool`, `String`, and `&str`.
/// Other expression-like values should be wrapped in `( ... )` for nested expressions.
