scanUntilBoundary(

buf: Uint8Array,

dashBoundary: Uint8Array,

newLineDashBoundary: Uint8Array,

total: number,

eof: boolean,

): number | null

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

Parameters

buf: Uint8Array

dashBoundary: Uint8Array

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.

number | null

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