Feature Flags

Feature	Description
dev_urandom_fallback (default)	This is only applicable to Linux. On Linux, by default, ring::rand::SystemRandom will fall back to reading from /dev/urandom if the getrandom() syscall isn't supported at runtime. When the dev_urandom_fallback feature is disabled, such fallbacks will not occur. See the documentation for rand::SystemRandom for more details.
use_heap (default)	Enable features that require use of the heap, RSA in particular.
