/**
|
|
* @name hexToU8a
|
|
* @summary Creates a Uint8Array object from a hex string.
|
|
* @description
|
|
* `null` inputs returns an empty `Uint8Array` result. Hex input values return the actual bytes value converted to a Uint8Array. Anything that is not a hex string (including the `0x` prefix) throws an error.
|
|
* @example
|
|
* <BR>
|
|
*
|
|
* ```javascript
|
|
* import { hexToU8a } from '@pezkuwi/util';
|
|
*
|
|
* hexToU8a('0x80001f'); // Uint8Array([0x80, 0x00, 0x1f])
|
|
* hexToU8a('0x80001f', 32); // Uint8Array([0x00, 0x80, 0x00, 0x1f])
|
|
* ```
|
