Use FormData instead. See https://doc.deno.land/deno/stable/~/FormData and https://developer.mozilla.org/en-US/docs/Web/API/FormData for more details.

Scans buf to identify how much of it can be safely returned as part of the PartReader body.

import { scanUntilBoundary } from "https://deno.land/std@0.141.0/mime/multipart.ts";

Parameters

buf: Uint8Array
  • The buffer to search for boundaries.
dashBoundary: Uint8Array
  • Is "--boundary".
newLineDashBoundary: Uint8Array
  • Is "\r\n--boundary" or "\n--boundary", depending on what mode we are in. The comments below (and the name) assume "\n--boundary", but either is accepted.
total: number
  • The number of bytes read out so far. If total == 0, then a leading "--boundary" is recognized.
eof: boolean
  • Whether buf contains the final bytes in the stream before EOF. If eof is false, more bytes are expected to follow.

Returns

number | null

The number of data bytes from buf that can be returned as part of the PartReader body.
