Subject: [PATCH v2 0/2] rust: take advantage of newer rust-analyzer
 features

As discussed in [1], we need to support multiple versions of
rust-analyzer to take advantage of newer features without breaking
compatibility for users on older toolchains; we must maintain support
for rust-analyzer v0.3.1940 (2024-04-29), which corresponds to our
current MSRV of 1.78.

Hence, this series revises the approach taken in [2] by first adding
multi-version support for rust-analyzer. Specifically, it enables
support for the v0.3.2727 (2025-12-22) release and newer, which is
required to resolve inherent method resolution issues for primitive
types found in recent versions of rust-analyzer.

Thanks to Gary Guo and Miguel Ojeda for their feedback and reviews.
