JFC. When will open source projects like @rustlang learn that putting toxic people like this in positions of ANY authority is unacceptable. https://github.com/marshallpierce/rust-base64/issues/213 . He's showing you who he is, and you're not listening.

https://crates.io/crates/syslog-ng-common/0.7.0

The colleague, who added @rustlang support to #syslog\_ng left many years ago. Syslog-ng #Rust support was last touched 7 years ago. Still, there are regular downloads. Just #searchengines or there are real users? Does it actually work?

I'm working on a cli for a service I've made that maintains a node edge graph (think neo4j type thing). I want to be able to display a graph in the terminal in a sort of ascii art text form kinda like git log -graph. I haven't found any third part libraries that can do that and am looking for help.

serde_derive now ships a precompiled binary. This made a lot of people angry. The crate maintainer finally locked the issue.

I recently ran into an issue where I wanted to use Any for slices. However, it only allows 'static types (based on what I read, this is because you get the same TypeId regardless of lifetimes).

I came up with this workaround which I think is safe:

```rust use std::{ any::{Any, TypeId}, marker::PhantomData, };

#[derive(Clone, Debug)] pub struct AnySlice<'a> { tid: TypeId, len: usize, ptr: *const (), marker: PhantomData<&'a ()>, }

impl<'a> AnySlice<'a> { pub fn from_slice(s: &'a [T]) -> Self { Self { len: s.len(), ptr: s.as_ptr() as *const (), tid: TypeId::of::(), marker: PhantomData, } }

pub fn as_slice(&self) -> Option<&'a [T]> { if TypeId::of::() != self.tid { return None; } Some(unsafe { std::slice::from_raw_parts(self.ptr as *const T, self.len) }) }

pub fn is(&self) -> bool { TypeId::of::() == self.tid } } ```

edit: Unfortunately it seems like Lemmy insists on mangling the code block. See the playground link below.

T: Any ensures T is also 'static. The lifetime is preserved with PhantomData. Here's a playground link with some simple tests and a mut version: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=3116a404c28317c46dbba6ed6824c8a9

It seems to pass Miri, including the mut version (which requires a bit more care to ensure there can only be one mutable reference). Any problems with doing this?

I’ve been working on a new search engine system that’s fully peer-to-peer, with no trusted third party.

The goal is the index IPFS, a torrent-like file sharing system for all kinds of media

It's written in Rust using libp2p. There is a daemon but it will eventually run in the browser with wasm

As of right now bitcoin crate is not deprecated, instead libs.rs responds with error 502.

Hi, I Just started working on a Emacs-inspired text editor in Rust.

Being insipred by Emacs, the most important part Is the possibiliy to implement new components.

My ideas were:

• Rust-based scripting language, like Rhai
• RustPython (slower, but more compatible and lots of people know Python)
• PyO3 (Bigger executable and not that fast)
• Wasm/Wasi (Cross-platform, but I don't know if the compatibility with Rust's hosted functions and structs is good)
• Other binded language, like V8, Lua or SpiderMonkey
• Compiled plugins, like .so or .DLL (Fast, but not compatible; there should be Rust plugin frameworks for implementing this, but I don't remember the name)

The elements to analyze are: speednees (consider it's a text editor, so...), easy-to-develop and Cross-platform (if possible, not that important), but the possibility to execute functions in the host Rust program is EXTREMELY important.

Thoughts?

Thanks in Advance.
