error[E0554]: when compiling tarpc crate

error[E0554]: #[feature] may not be used on the stable release channel

#![feature(plugin_registrar, rustc_private)]

I don’t want to be rude, but a little more information about what you are trying to do and what you don’t understand from this error message would help you to get better feedback and answers.

Nevertheless, the compiler tells you that you (or better tarpc) try to use feature attributes, which won’t not work with a release (or beta) version of the compiler. The solution is to use the nightly rust compiler.

Also, have a look at the error description here:

Thanks for the reply, and no you are not being rude. I will try using the nightly rust compiler and if the program still does not compile i will provide more info.
