Merge "Update TEST_MAPPING" am: 30345e64d5 am: b8243e0ca2 am: cb605690ac am: 1ad2f107a5 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/rand_chacha/+/2125246 Change-Id: Ic22f61489dc902e586a51a5cd18e21549db809a9 Signed-off-by: Automerger Merge Worker <android-build-automerger-merge-worker@system.gserviceaccount.com>
A cryptographically secure random number generator that uses the ChaCha algorithm.
ChaCha is a stream cipher designed by Daniel J. Bernstein[^1], that we use as an RNG. It is an improved variant of the Salsa20 cipher family, which was selected as one of the “stream ciphers suitable for widespread adoption” by eSTREAM[^2].
The RNGs provided by this crate are implemented via the fast stream ciphers of the c2-chacha crate.

rand_chacha is no_std compatible when disabling default features; the std feature can be explicitly required to re-enable std support. Using std allows detection of CPU features and thus better optimisation.
