linker-sections vs map-segments vs zeroize

Custom linker section memory initialization for no-std

Cargo subcommand to visualise ELF memory section layout against a linker memory map

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!
