Specifies PRNG key shape and operations.
A PRNG implementation is determined by a key type
K
and a collection of functions that operate on such keys. The key typeK
is an array type with element type uint32 and shape specified bykey_shape
. The type signature of each operations is:seed :: int[] -> K fold_in :: K -> int[] -> K split[shape] :: K -> K[*shape] random_bits[shape, bit_width] :: K -> uint<bit_width>[*shape]
A PRNG implementation is adapted to an array-like object of keys
K
by thePRNGKeyArray
class, which should be created via therandom_seed
function.
