Rust requires all methods of impl Trait to be in a single file, which
means we had a giant backend/mod.rs covering all exposed methods. By
using separate service definitions for the separate areas, and updating
the code generation, we can split it into more manageable chunks -
this commit starts with the scheduling code.
In the long run, we'll probably want to split up the protobuf file into
multiple files as well.
Also dropped want_release_gil() from rsbridge, and the associated method
enum. While it allows us to skip the thread save/restore and mutex unlock/
lock, it looks to only be buying about 2.5% extra performance in the
best case (tested with timeit+format_timespan), and the majority of
the backend methods deal with I/O, and thus were already releasing the
GIL.
- SearchTerm -> SearchNode
- Operator -> Joiner; share between messages
- build_search_string() supports specifying AND/OR as a convenience
- group_searches() makes it easier to negate
While implementing the overdue search, I realised it would be nice to
be able to construct a search string with OR and NOT searches without
having to construct each part individually with build_search_string().
Changes:
- Extends SearchTerm to support a text search, which will be parsed
by the backend. This allows us to do things like wrap text in a group
or NOT node.
- Because SearchTerm->Node conversion can now fail with a parsing error,
it's switched over to TryFrom
- Switch concatenate_searches and replace_search_term to use SearchTerms,
so that they too don't require separate string building steps.
- Remove the unused normalize_search()
- Remove negate_search, as this is now an operation on a Node, and
users can wrap their search in SearchTerm(negated=...)
- Remove the match_any and negate args from build_search_string
Having done all this work, I've just realised that perhaps the original
JSON idea was more feasible than I first thought - if we wrote it out
to a string and re-parsed it, we would be able to leverage the existing
checks that occur at parsing stage.
- use the TimestampSecs newtype instead of raw i64s
- use FixedOffset instead of a minutes_west offset
- check localOffset each time the timing is calculated, and set it
if it's stale - even for v1.
- check for and fix missing rollover when calculating timing
- stop explicitly passing localOffset in the sync/start call
