Methods

toState

toState(): [bigint, bigint, bigint, bigint]
Get the internal state as an array of 4 u64 values.

Returns [bigint, bigint, bigint, bigint]
- Defined in provenance-mark/src/xoshiro256starstar.ts:17

`Static`fromState

fromState(state: [bigint, bigint, bigint, bigint]): Xoshiro256StarStar
Create a new PRNG from a state array.
Parameters
- state: [bigint, bigint, bigint, bigint]
Returns Xoshiro256StarStar
- Defined in provenance-mark/src/xoshiro256starstar.ts:24

toData

toData(): Uint8Array
Serialize the state to 32 bytes (little-endian).

Returns Uint8Array
- Defined in provenance-mark/src/xoshiro256starstar.ts:31

`Static`fromData

fromData(data: Uint8Array): Xoshiro256StarStar
Create a new PRNG from 32 bytes of seed data (little-endian).
Parameters
- data: Uint8Array
Returns Xoshiro256StarStar
- Defined in provenance-mark/src/xoshiro256starstar.ts:45

nextU64

nextU64(): bigint

nextByte

nextByte(): number
Generate the next byte.

Returns number
- Defined in provenance-mark/src/xoshiro256starstar.ts:79

nextBytes

nextBytes(len: number): Uint8Array
Generate the next n bytes.
Parameters
