* Part 1 - Create as_edn_value function. * Do not include defaults inside output. * Pretty-printed by default. Do we want to make that a flag? * Includes simple test just to make sure it works. * Part 2 - only include ident if available. * Part 3 - Remove spacing and newlines as unnecessary. * Update function to build edn::Value directly rather than parsing from string * Update test to actually test the functionality. * Address review comments ncalexan. * Rename `as_edn_value` to `to_edn_value`. * Move `db/src/values.rs` to `core/src/values.rs` so we can reference inside `core/src/ib.rs`. * Add `lazy-static` crate to core `Cargo.toml` * Expose `values` as a public module from `core`. * Update references to values in `db/src/bootstrap.rs` & `db/src/lib.rs`. * Add new static vars for `DB_FULLTEXT`, `DB_INDEX` & `DB_IS_COMPONENT`. * Use static vars exposed in `values` inside `to_edn_value`. * Remove `db/id` as key in attribute output and use `entid` as `db/ident` if no `ident` is found for that `entid`. * Update test to match new expected output. * Add doc comment for function * Address review comments ncalexan. * Update function docstring to give clearer description of function. * Do not all entid at all to output. * Clean up code fetching ident (make it rustier). * Address review comments rnewman. * Extract out to new `to_edn_value` functions code for creating `edn::Value`\'s for `ValueType` and `Attribute`. * Use `map()` to create schema edn value rather than a loop. * Address review comments rnewman. * pass cloned instance of ident to `Attribute::get_edn_value`. * update `use` import for `edn`. * remove unnecessary call when using ident as key on `associate_ident`. * Fixed bug whereby we didn't differentiate between `db.index/value` and `db.index/identity` when generating `edn::Value` * Add extra assert at the end to ensure we get the same output when we convert the same schema to edn multiple times * Move check for type of uniqueness to `match` statement. * Also use `iter` instead of `into_iter` when iterating schema map.
