type parameters must be declared prior to const parameters

Hi Guys,

I am trying to install winsfs at our local Redhat cluster and I am experiencing some problems.
Everything goes well until this it starts to Compiling winsfs-core v0.1.0.

I am just posting the error messages below to check whether this is something you have seen before:

Thanks for the report.

It looks like you might have an older version of rust installed - could you try updating to the latest stable rust and building again?

If you have installed the rust toolchain in the usual way, this should just be rustup update.

Let me know if the problem persists.

EDIT: I've added the minimum support Rust version (1.62) in the crate metadata, so the error message should be better now.

It did help...
Sorry for the trouble :-) ( I should have checked myself at first...)
