Trait rand_core::block::BlockRngCore [−][src]
A trait for RNGs which do not generate random numbers individually, but in
blocks (typically [u32; N]
). This technique is commonly used by
cryptographic RNGs to improve performance.
See the module documentation for details.

Results type. This is the ‘block’ an RNG implementing BlockRngCore
generates, which will usually be an array like [u32; 16]
.
