Enum Emit 

pub enum Emit {
    Nothing,
    Part(Vec<u8>),
    Object(CompletedObject),
}

What a push produced.

Three outcomes rather than an Option, because “a part is ready to upload” and “the object is finished” are different instructions to the sink: the first frees memory mid-object, the second closes it.

Variants

Nothing

Keep accumulating.

Part(Vec<u8>)

A multipart part is full. Upload it and drop it — this is what keeps peak memory at O(part size) instead of O(object size) when the object cap is large or unset.

Object(CompletedObject)

The object reached its record/byte cap.
