import { Buffer } from "https://deno.land/std@0.190.0/streams/buffer.ts";
Returns a slice holding the unread portion of the buffer.
The slice is valid for use only until the next buffer modification (that
is, only until the next call to a method like read()
, write()
,
reset()
, or truncate()
). If options.copy
is false the slice aliases
the buffer content at least until the next buffer modification, so
immediate changes to the slice will affect the result of future reads.
