pub trait SingleValue: SqlType { }Expand description
A marker trait indicating that a SQL type represents a single value, as opposed to a list of values.
This trait should generally be implemented for all SQL types with the exception of Rust tuples. If a column could have this as its type, this trait should be implemented.
§Deriving
This trait is automatically implemented by #[derive(SqlType)]
