I meant "link rust-analyzer executable into a directory which is covered
by PATH environment variable". Typically, rust programmers have
~/.cargo/bin directory added to PATH env variable. So the official
rust-analyzer documentation suggests that either you link rust-analyzer
to this location or run using command `rustup run stable rust-analyzer'.
