Description

VSCode has a feature where multiple "folders" can be part of the same "workspace" (shown in the same window, basically). for the most part, this works out of the box with rust-analyzer. however, RA doesn't allow settings to be configured per-folder, only per-workspace.

the toml extension i'm using allows per-folder settings, so presumably this is under the control of the extension. it would be nice if it were supported by RA.

Research direction

Start by reading the VSCode multiroot workspace documentation linked in the issue and tracing rust-analyzer's workspace settings handling. Compare the behavior with the TOML extension mentioned in the report. Done means rust-analyzer accepts and applies settings independently for each folder in a multi-root workspace.
