Feature Flags

Feature Description
alloc (default) Enable features that require use of the heap, RSA in particular.
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.
std Enable features that use libstd, in particular `std::error::Error` integration.
