Are we embedded yet? - Blog - Tweede golf
Rust is maturing and every year more software is being made with it. In fact, Rust can be used as a competitor to C. In this article I will argue that this is now also the case for embedded Rust! Updated Jan 2024 With the rise of the connectivity of embedded devices in 'IoT' and smart industry it's becoming increasingly important to write correct and secure software. Not only does Rust help us in

Heap Allocations - The Rust Performance Book
Press ↠or → to navigate between chapters Press S or / to search in the book Press ? to show this help Press Esc to hide this help Heap Allocations Heap allocations are moderately expensive. The exact details depend on which allocator is in use, but each allocation (and deallocation) typically involves acquiring a global lock, doing some non-trivial data structure manipulation, and possibly execut
Valgrind
To use this tool, you must specify --tool=dhat on the Valgrind command line. DHAT is primarily a tool for examining how programs use their heap allocations. It tracks the allocated blocks, and inspects every memory access to find which block, if any, it is to. It presents, on a program point basis, information about these blocks such as sizes, lifetimes, numbers of reads and writes, and read and w
