Memory safety and ownership - Rust for C-Programmers

One of Rust’s defining features is its ability to guarantee memory safety (no dangling pointers, no use-after-free, no data races) at compile time without requiring a garbage collector (GC). This is achieved through its ownership and borrowing system: This system eliminates many common bugs found in C/C++ related to manual memory management while providing performance comparable to C/C++. C relies on manual memory management (malloc, calloc, realloc, free). This gives programmers fine-grained control but makes it easy to introduce errors like memory leaks (forgetting free), double frees, use-after-free, and buffer overflows. Rust’s compiler acts as a vigilant checker, preventing these issues before the program even runs.
