Richard Newman e21156a754 Implement simple pull expressions (#638) r=nalexander ... * Refactor AttributeCache populator code for use from pull. * Pre: add to_value_rc to Cloned. * Pre: add From<StructuredMap> for Binding. * Pre: clarify Store::open_empty. * Pre: StructuredMap cleanup. * Pre: clean up a doc test. * Split projector crate. Pass schema to projector. * CLI support for printing bindings. * Add and use ConjoiningClauses::derive_types_from_find_spec. * Define pull types. * Implement pull on top of the attribute cache layer. * Add pull support to the projector. * Parse pull expressions. * Add simple pull support to connection objects. * Tests for pull. * Compile with Rust 1.25. The only choice involved in this commit is that of replacing the anonymous lifetime '_ with a named lifetime for the cache; since we're accepting a Known, which includes the cache in question, I think it's clear that we expect the function to apply to any given cache lifetime. * Review comments. * Bail on unnamed attribute. * Make assert_parse_failure_contains safe to use. * Rework query parser to report better errors for pull. * Test for mixed wildcard and simple attribute.		2018-05-04 12:56:00 -07:00
