primitives/Slot

Type Aliases

SlotType

SlotType = bigint & object

Defined in: src/primitives/Slot/SlotType.ts:13 Slot type Represents a consensus layer slot number (12 seconds per slot). Slots are the fundamental unit of time in Ethereum’s proof-of-stake consensus.

Type Declaration

[brand]

readonly [brand]: "Slot"

See

https://voltaire.tevm.sh/primitives/slot for Slot documentation
https://github.com/ethereum/consensus-specs for Consensus specifications

Since

0.0.0

Variables

Slot

const Slot: object

Defined in: src/primitives/Slot/index.ts:11

Type Declaration

equals()

equals: (a, b) => boolean

Check if Slot values are equal

Parameters

a

SlotType First slot

b

SlotType Second slot

Returns

boolean true if equal

See

https://voltaire.tevm.sh/primitives/slot for Slot documentation

Since

0.0.0

Throws

Example

import * as Slot from './primitives/Slot/index.js';
const a = Slot.from(1000000n);
const b = Slot.from(1000000n);
const result = Slot.equals(a, b); // true

from()

from: (value) => SlotType

Create Slot from number, bigint, or string

Parameters

value

Slot number (number, bigint, or decimal/hex string) string | number | bigint

Returns

SlotType Slot value

See

https://voltaire.tevm.sh/primitives/slot for Slot documentation

Since

0.0.0

Throws

If value is negative or invalid

Example

import * as Slot from './primitives/Slot/index.js';
const slot1 = Slot.from(1000000n);
const slot2 = Slot.from(1000000);
const slot3 = Slot.from("0xf4240");

toBigInt()

toBigInt: (slot) => bigint

Convert Slot to bigint

Parameters

slot

SlotType Slot value

Returns

bigint BigInt representation

See

https://voltaire.tevm.sh/primitives/slot for Slot documentation

Since

0.0.0

Throws

Example

import * as Slot from './primitives/Slot/index.js';
const slot = Slot.from(1000000);
const big = Slot.toBigInt(slot); // 1000000n

toEpoch()

toEpoch: (slot) => EpochType

Convert Slot to its corresponding Epoch Each epoch contains 32 slots. This function performs integer division: epoch = slot / 32.

Parameters

slot

SlotType Slot value

Returns

EpochType Epoch value

See

https://voltaire.tevm.sh/primitives/slot for Slot documentation

Since

0.0.0

Throws

Example

import * as Slot from './primitives/Slot/index.js';
const slot = Slot.from(96n); // slot 96
const epoch = Slot.toEpoch(slot); // epoch 3 (96 / 32)

toNumber()

toNumber: (slot) => number

Convert Slot to number

Parameters

slot

SlotType Slot value

Returns

number Number representation

See

https://voltaire.tevm.sh/primitives/slot for Slot documentation

Since

0.0.0

Throws

If slot exceeds safe integer range

Example

import * as Slot from './primitives/Slot/index.js';
const slot = Slot.from(1000000n);
const num = Slot.toNumber(slot); // 1000000

Functions
