Richard Newman 2614f498be Ergonomics improvements, including a kw macro. (#537) r=emily ... * Add TypedValue::instant(micros). * Add From<f64> for TypedValue. * Add lookup_values_for_attribute to Conn. * Add q_explain to Queryable. * Expose an iterator over FindSpec's columns. * Export edn from mentat crate. Export QueryExecutionResult. * Implement Display for Variable and Element. * Introduce a `kw` macro. This allows you to write: ```rust kw!(:foo/bar) ``` instead of ```rust NamespacedKeyword::new("foo", "bar") ``` … and it's more efficient, too. Add `mentat::open`, eliminate use of `mentat_db` in some places.		2018-02-01 09:27:23 -08:00
