Struct Xoroshiro128State

Represents the complete serializable internal state of a Xoroshiro128Plus random number generator. Capturing this struct and passing it back to SetState(Xoroshiro128State) fully restores the generator to the exact point it was when the snapshot was taken, enabling deterministic save/load and replay.

Syntax

[Serializable]
public struct Xoroshiro128State

Remarks

The two 64-bit state words correspond directly to the s[0] and s[1] fields of the reference xoroshiro128+ algorithm (Vigna/Blackman). The state must never be all-zeros; SetState(Xoroshiro128State) enforces this invariant automatically.

Fields

S0

The first 64-bit word of the xoroshiro128+ generator state (s[0]). Combined with S1 in the plus-output step to produce the raw output value before the state transition occurs.

Declaration

public ulong S0

Field Value

Type	Description
ulong

S1

The second 64-bit word of the xoroshiro128+ generator state (s[1]). Receives a left-rotation and XOR operations during each step; set to 1 as a fallback when the full state would otherwise be all-zeros.

Declaration

public ulong S1

Field Value

Type	Description
ulong
