function readRangeSync
import { readRangeSync } from "";

Read a range of bytes synchronously from a file or other resource that is readable and seekable. The range start and end are inclusive of the bytes within that range.

import { assertEquals } from "";
import { readRangeSync } from "";

// Read the first 10 bytes of a file
const file = Deno.openSync("example.txt", { read: true });
const bytes = readRangeSync(file, { start: 0, end: 9 });
assertEquals(bytes.length, 10);
