Configuring rust-analyzer?

[justDeeevin]

So vim.languages.rust.lsp.opts is just a string, which I thought was odd. looking through the code, though, it seems like that option actually has no effect!!

I have a couple of settings I want to change for rust-analyzer. How can I do that?

Language module has been due a refactor for a while now, we're looking to make all language servers more customizable. CC @diniamo on this.

Though using Lua, you can extend the rust-analyzer configuration using vim.list_extend()

does that function directly modify the table or just return the modified table? in other words, could i just call the function or would i have to set the table i want to extend to the return value of the function?

It returns the mutated table.

Though looking into it now, we use rustaceanvim to set up rustanalyzer, which might not be as frictionless. I'm going to look into adding an option for rust analyzer options in rustaceanvim to make this easier.

Edit: depending on your needs (i.e. what you need to modify) modifying vim.globals.rustaceanvim may do the job for you. Regardless, I'll look into adding the option.
