Hello Rustacean!

Welcome to another edition of the Rust Bytes newsletter. In this issue, we’ll discuss May Rust job report, present a Rust challenge, spotlight an amazing Rust project, and highlight some incredible links of the week.

Welcome to issue 33.

THE MAIN THING

Rust Jobs Report (May 2024)

Just like that surprise free donut at WWDC (looking at you, Apple!), the May Rust Jobs Report is here and it’s bursting with good news.

The Filtra team analyzed the current state of Rust job market — here’s the TL;DR from their May 2024 report.

• Jobs Galore: Filtra team found a whopping 815 Rust jobs out there — that’s a slight bump despite the usual summer slowdown. Looks like companies are waking up to the power of memory-safe awesomeness.
• Who’s Hiring? The usual suspects like Amazon, Microsoft, and DataDog are still top dogs, but there are some new players on the block. Big shoutout to Tesla for joining the Rust party.
• Rust for Everything: From cloud infrastructure to building spreadsheets with WASM (looking at you, Quadratic!), Rust is everywhere.
• Junior Devs Welcome (Kinda): There aren’t tons of entry-level gigs, but mid-level devs are in high demand. Newbies, don’t despair! Check out some internship programs or consider building your skills in another language first.

Want the nitty-gritty details? Head over to the Filtra blog for the full report.

CHALLENGE: RUST QUIZ❓

Memory-Efficient String Reversal

Write a function named string_reversal in Rust that reverses a given string slice (&str) in-place.

Constraints:

• The function cannot allocate any new memory on the heap (no String::from or Vec::from).
• The function should modify the original string slice characters directly.

Expected Behavior:

• The function should take a mutable string slice (&mut str) as input.
• The function should reverse the order of characters within the input string slice.
• The reversal should happen within the same memory location as the original string.

Example:

• Input: "Rust Bytes!"
• Expected Output: "!setyB tsuR"

Bonus:

• Consider handling empty strings and single-character strings appropriately.

Share your solution in the reply and link your code snippet as a Rust playground.

PROJECT SPOTLIGHT 💡

Chroma

Chroma is the AI-native open-source vector database. Chroma makes it easy to build LLM apps by making knowledge, facts, and skills pluggable for LLMs.

Here’s what Chroma offers:

• Blazing-fast queries with embeddings to enable efficient nearest neighbor searches for your text data.
• Simplicity at its finest with a concise API with only a few core functions to let you focus on your project, not wrestling with complex code.
• Flexible embeddings to enable you utilize Chroma’s built-in options, integrate your own custom embeddings, or mix and match for maximum flexibility.
• Chroma seamlessly integrates with popular tools like LangChain and LlamaIndex, expanding your capabilities.

And if that’s not all, Chroma is Open Source, so no vendor lock-in, just pure embedding power at your fingertips.
