Exception handling in rustc_codegen_cranelift
Panics in Rust by default unwind to run Drop implementations for all values on the stack. Rust's stack unwinding is implemented using the same mechanism as C++ exceptions on most platforms. Recently the Cranelift code generator got support for "landingpad" style exceptions as detailed in the corresponding Cranelift RFC allowing me to add support for unwinding on panics to rustc_codegen_cranelift (cg_clif) for Unix systems.
In this article, I'll show you how exception handling works in cg_clif by walking you through several layers of the compilation process all the way to the runtime behavior.
Open-source work
zlib-rs
zlib-rs is a memory-safe Rust implementation of zlib, the widely-used compression library, used primarily on the web to provide gzip compression to the text/html/js/css we send around.
The initial development of zlib-rs was started and partly funded by Prossimo. It's now governed by the Trifecta Tech Foundation as part of their Data Compression initiative.
