Enum EmitPart 

pub enum EmitPart<'a> {
    Chunk(&'a Chunk),
    Verbatim(&'a [u8]),
    Form(&'a [u8]),
}

One child for partial_emit: a parsed Chunk to re-frame, a verbatim byte slice copied as-is, or a nested FORM container framed from its body.

Variants

Chunk(&'a Chunk)

Re-frame this chunk through the canonical emitter (8-byte header, payload, word-alignment pad).

Verbatim(&'a [u8])

Copy these bytes into the FORM payload verbatim. Use this for children whose bytes must be preserved exactly (the byte-preserving path); any word-alignment pad is added by partial_emit if the slice has odd length, so callers may pass either padded or unpadded child blocks.

Form(&'a [u8])

Frame a nested FORM container whose body is given verbatim. body starts with the 4-byte secondary id (DJVU/DJVI/THUM/…); the seam writes the FORM tag, the big-endian length, the body, and the word-alignment pad. Use this for the component sub-FORMs of a bundle so the FORM framing is never hand-rolled at the call site (and so the component’s start offset is reported by partial_emit_with_offsets).
