Hi Guys,
I've been interested in Rust for some time now (and even more, now
that
I've learned about functional programming and studied the lambda
calculus
at university ;)
I have 2 questions regarding the state and future of Rust on fedora:
1) Is there support for building and distributing rust libraries as
shared
libraries (.so files), if the crate supports it?
As far as I know at this moment it
doesn't really work properly and it
is also hard to support "features" because either you should build
shared library with support for all features or you build with minimal
and it seems not good idea.
If not, this could lead to at least one problem ... any software
package
using a rust library via a FFI (as described at [0]) would have to
build
the crate itself and bundle the library. I don't think this is
feasible in
the long run (every package having to build the create itself and
every
package having to include the .so file looks like a lot of wasted
work,
time and space to me).
Additionally, I generally dislike linking everything statically (like
golang does), and would much prefer if fedora supported building and
distributing rust libraries from the start. ;)
2) Is there a tool for generating .spec files / srpms from crates
(like
gofed, but nicer), and is such a tool planned?
Not yet and probably it will be very
simple since I want to have all
BuildRequires/Requires/Provides generation in RPM and not in some
external tools. So work on this tool will be just get version, summary
and create spec from very simple template.
If nobody has started working on that yet, I'd volunteer. It sounds
like a
fun project!
Stop by our IRC channel and we can discuss it ;)
