Upgrade zeroize to 1.6.0 am: a7a12dcfc5 am: 2f2a496571 am: 8d0b20ba8d am: f20bd54655 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/zeroize/+/2513819 Change-Id: I2feb5b5b394af2b4b88eefcb5f2cd083820e6ff4 Signed-off-by: Automerger Merge Worker <[email protected]>
Securely zero memory (a.k.a. zeroize) while avoiding compiler optimizations.
This crate implements a portable approach to securely zeroing memory using techniques which guarantee they won't be “optimized away” by the compiler.
The Zeroize trait is the crate's primary API.
Zeroing memory securely is hard - compilers optimize for performance, and in doing so they love to “optimize away” unnecessary zeroing calls. There are many documented “tricks” to attempt to avoid these optimizations and ensure that a zeroing routine is performed reliably.
This crate isn‘t about tricks: it uses core::ptr::write_volatile and core::sync::atomic memory fences to provide easy-to-use, portable zeroing behavior which works on all of Rust’s core number types and slices thereof, implemented in pure Rust with no usage of FFI or assembly.
#![no_std] i.e. embedded-friendly!Rust 1.56 or newer.
In the future, we reserve the right to change MSRV (i.e. MSRV is out-of-scope for this crate's SemVer guarantees), however when we do it will be accompanied by a minor version bump.
