import { copy } from "https://deno.land/std@0.190.0/bytes/copy.ts";
Copy bytes from the src
array to the dst
array. Returns the number of
bytes copied.
If the src
array is larger than what the dst
array can hold, only the
amount of bytes that fit in the dst
array are copied.
An offset can be specified as the third argument that begins the copy at
that given index in the dst
array. The offset defaults to the beginning of
the array.
