Thanks for providing those changes!

*If* the root folder (containing Cargo.toml) is also a (kate) projectBase, e.g. 
because it is the root of a git repo (as is probably the case AFAIK), then the 
following configuration should arrange that (barring some bug ;-) ):

{
         "global":
         {
                 "root": ""
         },
         "servers":
         {
                 "Rust":
                 {
"command": "/home/user/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/bin/rls"
                 }
         }
}

The "global" section is inherited by each server part, and a (non-null) "root" 
is interpreted either as an absolute path or a relative path wrt projectBase 
(so, in this case = projectBase). If the Cargo.toml is not in a top-git 
directory, it could be turned into kate project(Base) by adding a .kateproject, 
which should then also work.

For now, that configuration behavior has been documented in code comments.  If 
that behavior/principle turns out to work well, then it obviously requires 
better documentation.  And if possible, have some UI that can convey that 
somehow ...

Mark.
