Struct diesel::sql_types::Nullable

pub struct Nullable<ST>(/* private fields */);

The nullable SQL type.

This wraps another SQL type to indicate that it can be null. By default all values are assumed to be NOT NULL.

ToSql impls

• Any T which implements ToSql<ST>
• Option<T> for any T which implements ToSql<ST>

FromSql impls

• Option<T> for any T which implements FromSql<ST>
