* Review comment: Fix typos; format; add TODOs.
* Review comment: Assert that Mentat `Schema` is valid upon creation.
* Review comment: Improve conversion to and from SQL values.
This patch factors the fundamental SQL conversion maps
between (rusqlite::Value, value_type_tag) and (edn::Value, ValueType)
through a new Mentat TypedValue. (A future patch might rename this
fundamental type mentat::Value.)
To make certain conversion functions infallible, I removed
placeholders for :db.type/{instant,uuid,uri}. (We could panic
instead, but there's no need to do that right now.)
* Review comment: Always uses bundled SQLite in rusqlite.
This avoids (runtime) failures in Travis CI due to old SQLite
versions. See 432966ac77.
* Review comment: Move semantics in `from_sql_value_pair`.
* Review comment: DB_EXCISE_BEFORE_T instead of ...BEFORET (no underscore).
* Review comment: Move overview notes to the Wiki.
* Test the mentat_query directory on Travis.
* Export common types from edn.
This allows you to write
use edn::{PlainSymbol,Keyword};
instead of
use edn:🔣:{PlainSymbol,Keyword};
* Add an edn::Value::is_keyword predicate.
* Clean up query, preparing for query-parser.
* Make EDN keywords and symbols take Into<String> arguments.
* Implement parsing of simple :find lists.
* Rustfmt query-parser. Split find and query.
* Review comment: values_to_variables now returns a NotAVariableError on failure.
* Review comment: rename gimme to to_parsed_value.
* Review comment: add comments.
Starting to work out the project layout for sub-crates. The crate inside query-parser/ is "datomish-query-parser" and the core code in src/ depends on it.
