type t

Low-level type for xoshiro256++. This is basically an int64 array of 4 values.

val of_int64_array : int64 array -> t

Copy an int64 array to the state.

raises Invalid_argument
if the array is not of size 4.

val to_int64_array : t -> int64 array

Copy the state to an int64 array.

val next : t -> int64

val jump : t -> unit

This is the jump function for the generator. It is equivalent to 2¹²⁸ calls to next; it can be used to generate 2¹²⁸ non-overlapping subsequences for parallel computations.

val long_jump : t -> unit

This is the long-jump function for the generator. It is equivalent to 2¹⁹² calls to next; it can be used to generate 2⁶⁴ starting points, from each of which jump will generate 2⁶⁴ non-overlapping subsequences for parallel distributed computations.
