These expand into a collection of named variables that should be
passed via bind parameters when the query is executed.
Bind parameters are now only named.
* Implement pretty printing
Signed-off-by: Victor Porof <victor.porof@gmail.com>
* Rewrite pretty printing.
This does a few things. First, it use pretty.rs directly, without the
layer of macro obfuscation. The code is significantly simpler as a
result.
Second, it tightens the layout, using pretty.rs to group nested
layouts that fit on a single line. This is Clojure's EDN style, more
or less.
Third, it drops "special format" support for queries. This wasn't
completely implemented; if we want it, we can newtype
Query(edn::Value) and figure out how to really implement this idea.
* Rename to reflect functionality.
* Make write interface more Rust-like.
There isn't a clear standard in the stdlib, but a function that takes
ownership of a writer and then returns it back is definitely not
Rust-like. That's what a (mutable) reference is for.
* Review comment: Use as_ref to avoid cloning strings.
* Post: Fix tests to use `without_spans()`.
Printing out failure to meet rustc version helps users during
setup with a helpful message if using an older rustc.

* Pre: Implement batch [a v] pair lookup.
* Pre: Add InternSet for sharing ref-counted handles to large values.
* Pre: Derive more for Entity.
* Pre: Return DB from creating; return TxReport from transact.
I explicitly am not supporting opening existing databases yet, let
alone upgrading databases from earlier versions. That can follow fast
once basic transactions are supported.
* Pre: Parse string temporary ID entities; remove ValueOrLookupRef.
This adds TempId entities, but we can't disambiguate String temporary
IDs from values without the use of the schema, so there's no new value
branch. Similarly, we can't disambiguate lookup-ref values from two
element list values without a schema, so we remove this entirely.
We'll handle the ambiguity later in the transactor.
* Persist partitions to SQL store; allocate transaction ID. (#186)
* Post: Test upserting with vectors.
This converts an existing test to EDN:
84a80f40f5/test/datomish/db_test.cljc (L193).
* Implement tempid upsert resolution algorithm. (#184)
* Post: Separate Tx out of DB.
This is very preliminary, since we don't have a real connection type
to manage transactions and their metadata yet.
* Post: Comment on implementation choices in the transactor.
* Review comment: Put long use lists on separate lines.
* Review comment: Accept String: Borrow<S> instead of just String.
* Review comment: Address nits.
* Move Schema from mentat_db to mentat_core.
* Define SchemaMap in terms of Entid, not i64.
* Add Schema::{is_attribute,identifies_attribute}.
* Add pointer to #291.
* Don't pass around 64-bit pointers to 64-bit integers.
* Leave a pointer to issue 288.
* Re-export mentat_db::types::DB from mentat_db.
* Parse EDN strings in the query parser.
* Export 'public' API from mentat_query_parser's top level.
* Stub out mentat::q_once.
