Nick Alexander cbffe5e545 Use rust-peg for tx parsing. ... There are few reasons to do this: - it's difficult to add symbol interning to combine-based parsers like tx-parser -- literally every type changes to reflect the interner, and that means every convenience macro we've built needs to chagne. It's trivial to add interning to rust-peg-based parsers. - combine has rolled forward to 3.2, and I spent a similar amount of time investigating how to upgrade tx-parser (to take advantage of the new parser! macros in combine that I think are necessary for adapting to changing types) as I did just converting to rust-peg. - it's easy to improve the error messages in rust-peg, where-as I have tried twice to improve the nested error messages in combine and am stumped. - it's roughly 4x faster to parse strings directly as opposed to edn::ValueAndSpan, and it'll be even better when we intern directly.		2018-05-10 10:24:05 -07:00
