Not sure what you mean, doesn't Rust have a runtime now?

Everything has a runtime, except perhaps hand-rolled assembly. Rust today has a C-like runtime, which is bare minimum and makes it possible to FFI easily. For the most part you can pretend it doesn't exist; it doesn't affect programs.

In the past, Rust did have a bulkier runtime with a green thread scheduler and libuv; a runtime that "mattered".

It has a runtime comparable to C. Back in those days, it had a much larger one.

Ok, that's what I thought : )

It interesting that they stripped down the runtime from previous(larger) iterations. Are those discussion discussed anywhere that you know about? It seems like that would be an interesting read.

https://github.com/rust-lang/rfcs/blob/master/text/0230-remo... and the PR/issue linked there.

There are also old mailing list discussions on rust-dev somewhere which discuss this IIRC.
