growingv0.1.1
Implementation of volatile pointers for I/O device access

zeroize
growingv1.8.2
Securely clear secrets from memory with a simple trait built on stable Rust primitives which guarantee memory is zeroed using an operation will not be 'optimized away' by the compiler. Uses a portable pure Rust implementation that works everywhere, even WASM!
