RustConf 2019 - Rust for Weld, a High Performance Parallell JIT Compiler by Shoumik Palkar
Weld is an open source Rust project that accelerates data-intensive libraries and frameworks by as much as 100x. It does so by JIT-compiling a custom parallel intermediate representation and optimizing across functions within a single library as well as across different libraries, so developers can write modular code and still get close to bare metal performance without incurring expensive data movement costs. We first describe our use of Rust to build an extensible, performance sensitive compiler for Weld. In particular, we discuss challenges in writing a native code generator with LLVM in Rust, challenges in reducing JIT compilation times within our compiler, and architecting the compiler for both extensibility using Rust's powerful trait system, but also portability of our library across other languages, such as Python and C. Finally, we discuss our experiences with building a parallel runtime in Rust, and the unique challenges associated with calling unsafe Rust from JIT'd code.
A mix of topics of casting, shadowing, constants and static variables inside the Rust Programming Language. This Rust programming language tutorial series is aimed at easing your training step by step.

Hello everyone, recently I have come across a feature in Rust, known as non_exhaustive. It was introduced in Rust 1.40.0 . This attribute prevents source code-breaking changes in projects downstream.
Rust vs Go - Which Is More Popular - Go and Rust are two of the hottest compiled programming languages. I develop in Go full-time and love it, and I'm learning more about Rust recently - its an exc
We love Rust at Wasmer! We’ll overview how Rust development in 2019 has impacted us as a small company using a lot of advanced Rust features for our WebAssembly runtime and tools, what we’re thankful for in Rust this year, the problems we face, and what we would like to see in the future.
