Compiling error #8

Closed rwbc closed 1 year ago

rwbc commented 2 years ago

Hello,

I get an error for compiling info.rs. This is on Win7 with Msys2 and cargo/rust package 1.57.0. I don't know much about Rust syntax and how format! works there, but the complained line is at the end of the built log.

Hey there!

This particular section uses a language feature that was introduced in Rust 1.58.

You should be able to fix this problem by upgrading your Rust toolchain, for example using rustup update.

Please let me know if you are running into any further issues!

Thanks for the info Tim,

I am surprised how often they still introduce new features in Rust ;-)

As this was just released a week ago I guess it might be available as a package for msys2 in the next two weeks. (msys2 has its own toolchains and package manager and offers a bash shell in WIN)

TimJentzsch commented 2 years ago

As Rust is still a relatively "new" language, a couple of features are not stabilized yet. I tried changing the corresponding call to make it compile for you, but I'm also using the unstable feature str_split_whitespace_as_str which is not available on the stable toolchain yet. Is there a way for you to use nightly Rust?

rwbc commented 2 years ago

Don't worry (no need to change your sources). I will report back after I have installed the next official rust package. Using 'nightly' would probably require a parallel installation, which would defeat the whole purpose of using msys2.

Thanks again.
