I'm working with an existing code base and there are quite a few
crates I need to bring in or find replacements for. I'm hoping to
minimise or isolate the changes I need to make to the existing code
base. Obviously, some changes are going to be unavoidable.

To start with, what I'd like to do is bring in a crate and build it as
a library and then link it with my module. I just need to work out the
magic incantation to do that.

Like I said, I'm interested in futures. Why it's useful: async Rust is
arguably more common and easier to use than other forms of
multi-threaded processing. Other crates that I'd like: anyhow,
bincode, byteorder, log, once_cell, pin-project, rand, serde, slab,
static_assertions, uuid plus some more esoteric ones.

At this stage, I'm really just experimenting to see what's possible.

Anyway, thanks for your response. I'll keep playing and see where I get to.

Kind regards,

Chris
