Struct StdEntropyGenerator 

pub struct StdEntropyGenerator(/* private fields */);

The standard entropy generator. It uses various os available operations to generate entropy:

• macos <- it utilizes getentropy syscall
• linux <- it utilizes getrandom syscall
• windows <- it utilizes ProcessPrng syscall

Other platforms are not supported at the moment.
