I need to use a Rust nightly feature with the VS-code Rust-language-server.
#![feature(generic_associated_types)]
So, I did
$ rustup default nightly
and, vscode rust extension automatically starts
$ rustup component add rls --toolchain nightly-x86_64-unknown-linux-gnu
however,
error: component 'rls' for target 'x86_64-unknown-linux-gnu' is unavailable for download for channel 'nightly'
Sometimes not all components are available in any given nightly.
I understand what it means, and is there nothing to do?
I mean looks like it’s impossible to code with Rust nightly feature in VS-code currently.
>Solution :
Use rust-analyzer instead. Rls is not in active now.
