This is needed to track anon const parents properly once we implement
`ConstArgKind::Path` (which requires moving anon const def-creation
outside of `DefCollector`):
Why do we need this in addition to [`Self::current_hir_id_owner`]?
Currently (as of June 2024), anonymous constants are not HIR owners;
however, they do get their own DefIds. Some of these DefIds have to be
created during AST lowering, rather than def collection, because we
can't tell until after name resolution whether an anonymous constant
will end up instead being a [`rustc_hir::ConstArgKind::Path`]. However,
to compute which generics are available to an anonymous constant nested
inside another, we need to make sure that the parent is recorded as the
parent anon const, not the enclosing item. So we need to track parent
defs differently from HIR owners, since they will be finer-grained in
the case of anon consts.

README.md
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 integrate 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).
