Engine

Defined in: src/engine/types.ts:14

A generator. Only nextUint32 is required; the optional members are detected once when the engine is adopted, and used as a fast path when present.

Properties

algorithm

readonly algorithm: string

Defined in: src/engine/types.ts:16

Identifies the algorithm in EngineState.

---

seedable

readonly seedable: boolean

Defined in: src/engine/types.ts:18

Whether the engine can be re-seeded. Math.random and the CSPRNG cannot.

Methods

clone()?

optional clone(): Engine

Defined in: src/engine/types.ts:29

Returns

Engine

---

fillBytes()?

optional fillBytes(out): void

Defined in: src/engine/types.ts:27

Parameters

out

Uint8Array

Returns

void

---

fillUint32()?

optional fillUint32(out): void

Defined in: src/engine/types.ts:26

Parameters

out

Uint32Array

Returns

void

---

getState()?

optional getState(): EngineState

Defined in: src/engine/types.ts:30

Returns

---

jump()?

optional jump(): void

Defined in: src/engine/types.ts:35

Advance as far as 2^(period/2) draws, for non-overlapping streams.

Returns

void

---

nextFloat64()?

optional nextFloat64(): number

Defined in: src/engine/types.ts:25

A uniform double in [0, 1) with 53 bits of precision.

Returns

number

---

nextUint32()

nextUint32(): number

Defined in: src/engine/types.ts:21

A uniform integer in [0, 2^32).

Returns

Defined in: src/engine/types.ts:23

Returns

bigint

---

reseed()?

optional reseed(seed): void

Defined in: src/engine/types.ts:33

Restart from new seed material, in place. Absent on unseedable engines.

Parameters

seed

Seed

Returns

void

---

setState()?

optional setState(state): void

Defined in: src/engine/types.ts:31

Parameters

state

EngineState

Returns

void

---

split()?

optional split(n): Engine[]

Defined in: src/engine/types.ts:37

Derive n independent generators.

Parameters

n

number

Returns

Engine[]
