compiler: Rename several types/traits for per-query vtables - Follow-up to https://github.com/rust-lang/rust/pull/151577 --- This is another round of renaming for some subtle types and traits used by the query system, to hopefully make them easier to understand. Key renames: - struct `DynamicQuery` → `QueryVTable` (the actual vtable-like structure) - struct `DynamicQueries` → `PerQueryVTables` (holds a vtable for each query) - trait `QueryConfig` → `QueryDispatcher` - (used by generic functions in `rustc_query_system` to interact with query vtables) - struct `DynamicConfig` → `SemiDynamicQueryDispatcher` - (implements `QueryDispatcher` by combining a vtable with some compile-time boolean flags for improved perf) - trait `QueryConfigRestored` → `UnerasedQueryDispatcher` - (provides a `QueryDispatcher` while also remembering the query's unerased value type; allows some per-query code to be moved out of macros and into generic functions) This was trickier than `DepKindVTable`, because there are more types and traits involved, and it's harder to come up with distinctive and useful names for all of them. There should be no change to compiler behaviour. r? Kivooeo (or compiler) |

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).
