Enum ObservationSelector 

pub enum ObservationSelector {
    ByteRange {
        offset: u64,
        len: u64,
    },
    PdfIndirectObject {
        object: u32,
        generation: u16,
    },
    PdfEncodedStream {
        object: u32,
        generation: u16,
    },
    PdfRevision {
        index: u32,
    },
}

A narrow observation of the reconstructed source.

Every selector resolves to a half-open output range [a, b) in the source address space (output offset O is source offset O, by the exact profile).

Variants

ByteRange

Raw output byte range [offset, offset + len).

Fields

offset: u64

First output byte.

len: u64

Number of bytes; must be non-empty.

PdfIndirectObject

The full physical byte extent of indirect object object generation (the N G obj introducer through endobj).

Fields

object: u32

PDF object number.

generation: u16

PDF generation number.

PdfEncodedStream

The physical encoded stream data span of the stream in indirect object object generation: the compressed bytes exactly as they appear in the source.

Fields

object: u32

PDF object number of the enclosing indirect object.

generation: u16

PDF generation number of the enclosing indirect object.

PdfRevision

Every source byte belonging to incremental-update revision index.

Fields

index: u32

Zero-based revision index.
