import { fn } from "https://deno.land/x/ddc_vim@v4.0.2/deps.ts";
const { bufwinid } = fn;
The result is a Number, which is the window-ID of the first
window associated with buffer {buf}. For the use of {buf},
see bufname() above. If buffer {buf} doesn't exist or
there is no such window, -1 is returned. Example:
echo "A window containing buffer 1 is " .. (bufwinid(1))
Only deals with the current tab page. See win_findbuf() for
finding more.
Can also be used as a method:
FindBuffer()->bufwinid()
