failed to load workspace in projects with Rust nested more than one directory deep

[ElykDeer]

rust-lang.rust's default behavior allowed for the discovery of Rust projects nested at any depth in large projects.

Now that rust-analyzer is the default for Rust in VSCode, I no longer get any Rust integration in my IDE for folders nested more than one level deep.

The year is 2022, and I should not need to populate configuration files or change settings for my IDE to provide support for the language I'm using. I feel strongly enough about this to assert that rust-analyzer is unusable for my (and many others') day-to-day use case and consider using a different IDE with reasonable default behavior.

I see the linkedProjects workaround provided in #7268 as well as the performance considerations in #2533, but unfortunately I don't think that rust-analyzer is a viable replacement for rust-lang.rust until I can just:

1. Open my project's root directory
2. Have support for all the Rust code in my project

rust-analyzer version: rust-analyzer version: 0.3.1170-standalone (b6d59f2bb 2022-08-14)
rustc version: rustc 1.63.0 (4b91a6ea7 2022-08-08)
relevant settings: All default settings, fresh install. Using VSCode.
