I have a Debian Buster and a FreeBSD 12.0 computer at home. On Linux I use Gnome Builder along with rustup components such as rls-preview installed. This allows me to utilzie code hints and code completion from within Builder.
On the FreeBSD computer, however it seems that rls-preview is not available. When I run "rustup component add rls-preview" the error message directs me to https://rust-lang.github.io/rustup-components-history/x86_64-unknown-freebsd.html which shows a nice table of components that are available for the freebsd tool chain.
I am wondering if it is possible to install or manually compile the rls-preview component some other way? I am not sure why it is not supported (I think is a tier level think) but if anyone has managed to get rls-preview or code completion installed/working in FreeBSD, I'd be grateful of any tips.
