Hi,

Rust has emerged as Linux’s second official language [0]. It's a clear win, and all the response from the big companies in the industry have been positive, e.g. [1].

D is trying to catch up, and Walter started the work on borrow checker ~3 years ago [2], but shall the D community wait for it? And even if it get into D, how much more man power are needed to build all these libraries [3]: 85,142 crates, 16,783,226,701 downloads? and how long you think it will take? Right now D has 2185 packages [4], by this rough estimate, the Rust community is ~40x time bigger than D's. (There is no total downloads stats on [4], so we do not know the actual D libraries usage).

While Walter is trying to join them, shall we D users ... use them ... now? :-) I think we should.

Rust has f.f.i to C, and there is a utility cbindgen [5] which can create C/C++11 headers for Rust libraries which expose a public C API; and on the D side, we have dpp [6] and dstep [7] to make D talks to C very easily. And of course, we also have -betterC :-)

So I just created this wrapper library to make those high performant, memory safe Rust library available to D users:

https://code.dlang.org/packages/rust_interop_d

and started with these 2 containers:

• DashMap: is an implementation of a concurrent associative array/hashmap in Rust. dashmap-5.3.4 Blazing fast concurrent HashMap for Rust. [8]
• SegQueue: An unbounded multi-producer multi-consumer queue. [9]

Since I'm new to Rust, I want to call for help / contributions if you know Rust and want to use some of their high quality libraries from D. Esp. since Rust does not have GC, those of you who want nogc D libraries now clearly have an alternative.

So, let's start D-Rusting :-)

well, if there's something that Rust is better but I can use D from D, hell yeah let's do it but i hope it's temporary tho

Yes, use rust to defeat rust.
