From e947a32c59bd9c3df055edf6f3334b653c679e11 Mon Sep 17 00:00:00 2001 From: Nick Alexander Date: Tue, 28 Mar 2017 14:38:31 -0700 Subject: [PATCH] Part 2: Use `value_and_span` apparatus in tx-parser/. I break an abstraction boundary by returning a value column `edn::ValueAndSpan` rather than just an `edn::Value`. That is, the transaction processor shouldn't care where the `edn::Value` it is processing arose -- even we care to track that information we should bake it into the `Entity` type. We do this because we need to dynamically parse the value column to support nested maps, and parsing requires a full `edn::ValueAndSpan`. Alternately, we could cheat and fake the spans when parsing nested maps, but that's potentially expensive. --- db/src/bootstrap.rs | 2 +- db/src/db.rs | 4 +- db/src/tx.rs | 6 +- tx-parser/src/errors.rs | 7 +- tx-parser/src/lib.rs | 438 +++++++++++++++++--------------------- tx-parser/tests/parser.rs | 12 +- tx/src/entities.rs | 5 +- 7 files changed, 214 insertions(+), 260 deletions(-) diff --git a/db/src/bootstrap.rs b/db/src/bootstrap.rs index 7e676dc3..d844d440 100644 --- a/db/src/bootstrap.rs +++ b/db/src/bootstrap.rs @@ -273,6 +273,6 @@ pub fn bootstrap_entities() -> Vec { // Failure here is a coding error (since the inputs are fixed), not a runtime error. // TODO: represent these bootstrap data errors rather than just panicing. - let bootstrap_entities: Vec = mentat_tx_parser::Tx::parse(&[bootstrap_assertions][..]).unwrap();
