`collect_active_jobs_from_all_queries` takes a `require_complete` bool, and then some callers `expect` a full map result while others allow a partial map result. The end result is four possible combinations, but only three of them are used/make sense. This commit introduces `CollectActiveJobsKind`, a three-value enum that describes the three sensible combinations, and rewrites `collect_active_jobs_from_all_queries` around it. This makes it and its call sites much clearer, and removes the weird `Option<()>` and `Result<QueryJobMap, QueryJobMap>` return types. Other changes of note. - `active` is removed. The comment about `make_frame` is out of date, and `create_deferred_query_stack_frame` *is* safe to call with the query state locked. - When shard locking failure is allowed, collection no longer stops on the first failed shard.
This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
