function encodeIntoHex(input: string | Uint8Array_ | ArrayBuffer, output: Uint8Array_): number

encodeIntoHex takes an input source and encodes it as hex into the output buffer.

input: string | Uint8Array_ | ArrayBuffer: the source to encode.
output: Uint8Array_: the buffer to write the encoded source to.

Returns

the number of bytes written to the buffer.

Example: Basic Usage

import { assertEquals } from "@ende/assert";
import {
  calcSizeHex,
  encodeHex,
  encodeIntoHex,
} from "@ende/encoding/unstable-hex";

const prefix = "data:url/fake,";
const input = await Ende.readFile("./ende.lock");
const output = new Uint8Array(prefix.length + calcSizeHex(input.length));

const o = new TextEncoder().encodeInto(prefix, output).written;
encodeIntoHex(input, output.subarray(o));
assertEquals(
  new TextDecoder().decode(output),
  "data:url/fake," +
    encodeHex(await Ende.readFile("./ende.lock")),
);
