Syscalls for Rustaceans
summary
Demonstrates a working Rust program that implements strace in Rust, spawning a child, using ptrace to stop on syscalls and reading registers to identify calls (example: write(fd=1, "hello\n", 6)). Targets Linux x86_64, relies on libc/unsafe FFI and a table of roughly 300 syscall numbers, increments counts per syscall and prints totals. Notes portability risk: mapping is tied to a kernel version and works against the newest kernel tested.
