Enum Source 

pub enum Source<'a> {
    Document,
    Carried {
        map: &'a Fragments,
        parent: &'a Source<'a>,
    },
    Plaintext {
        ciphertext: Span,
        parent: &'a Source<'a>,
    },
}

Scoped coordinates for callback views. Joins map to their enclosing source; decrypted bytes have their own coordinate space, never invented physical offsets. A caller can retain/project known locations while the scope is live.

Variants

Document

Original PFX document coordinates.

Carried

Logical carried bytes with their exact original fragment mapping.

Fields

map: &'a Fragments

Mapping into the parent source coordinates.

parent: &'a Source<'a>

The source enclosing those fragments.

Plaintext

New plaintext coordinates starting at zero, without a bytewise map to ciphertext (encryption is not a source-offset-preserving transformation).

Fields

ciphertext: Span

Ciphertext enclosure in the parent’s coordinates.

parent: &'a Source<'a>

Original source of that encrypted container.
