Select features

[Adrien-Bodineau]

Feature description

Would be nice to have a :RustAnalyzer features x,y,z command to select a set of features to activate.
and :RustAnalyzer all-features to enable all-features of a crate as it is currently done by :RustAnalyzer target xxx

Hey 👋

thanks for the suggestion. I fear that adding too many commands to change various rust-analyzer options at runtime could add more complexity/bloat than I'm comfortable with.

I don't think this is possible in VSCode, is it?
What are some alternative options to this (e.g. using :h .exrc, ...)?

Perhaps a more general way to change config options would be a more flexible solution?
Something like :RustAnalyzer config {path} {value} , for example, :RustAnalyzer config cargo.features = { "list", "of", "features" }

(folke/trouble.nvim has a nice parser that uses tree-sitter to parse Lua from command arguments using tree-sitter).

I'm going to add a triage label and keep this open.
PRs are welcome, but depending on the complexity, I might end up choosing not to merge.

I stumbled over this issue while researching for a solution on this topic. I am working with a multi-target rust codebase, where, depending on the compile feature, code get's activated or deactivated for one or the other target. So I have some need to be able to toggle through features quickly on runtime.
I am wondering, if there is already a robust workflow for this with the current feature set of rustaceanvim.

No, not without using the internal Lua modules, afaik.
