Enum ExistingDocumentPolicy 

pub enum ExistingDocumentPolicy {
    PreserveBase(PreserveBasePolicy),
    Reconstruct(ReconstructPolicy),
}

Explicit, type-safe policy for existing-document operations.

There is deliberately no Default implementation: every call site must choose preservation or reconstruction. Engine-specific policy values also cannot be assembled from arbitrary structure dispositions.

use oxidize_pdf::operations::ExistingDocumentPolicy;

let policy = ExistingDocumentPolicy::default();

Variants

PreserveBase(PreserveBasePolicy)

Preserve the first input byte-for-byte and control secondary structures.

Reconstruct(ReconstructPolicy)

Reconstruct page appearance/content and deliberately lose other semantics.

Implementations

impl ExistingDocumentPolicy

pub const fn preserve_base() -> Self

Preserve the base and reject ambiguous secondary structures.

pub const fn reconstruct() -> Self

Reconstruct page appearance/content and explicitly discard every detected document-level structure.

pub const fn reconstruct_with_metadata_from_first() -> Self

Reconstruct pages while copying document information from the first input.

pub const fn engine(self) -> ExistingDocumentEngine

Return the selected execution engine.

pub const fn with_page_labels(self, policy: DocumentStructurePolicy) -> Self

Configure page labels in secondary inputs of a preserving merge. Reconstructive policies are unchanged because they always discard them.
