Struct PdfACatalogSignals 

pub struct PdfACatalogSignals {
    pub mark_info_marked: bool,
    pub mark_info_user_properties: bool,
    pub mark_info_suspects: bool,
    pub has_struct_tree_root: bool,
    pub catalog_lang: Option<String>,
    pub output_intent_count: usize,
    pub has_xmp_metadata: bool,
}

Structural PDF/A signals from the catalog, independent of the XMP packet. Surfaced by pdfa_signals.

Use PdfAConformance::from_signals_and_xmp to combine these with the XMP packet’s pdfaid:part / pdfaid:conformance declaration into a single conformance picture.

Fields

mark_info_marked: bool

/MarkInfo /Marked — true when the catalog declares the document is logically structured (“tagged PDF” per §14.7.2). Required by PDF/A A-level conformance.

mark_info_user_properties: bool

/MarkInfo /UserProperties — true when user-properties are declared (PDF 1.6+). Not required by any PDF/A level, but surfaced for completeness.

mark_info_suspects: bool

/MarkInfo /Suspects — true when the document has suspect markings (PDF 1.6+). Recommended FALSE for PDF/A-2a / -3a.

has_struct_tree_root: bool

/StructTreeRoot reference present on the catalog. The dict’s contents (the actual tag tree) is NOT walked here.

catalog_lang: Option<String>

/Lang on the catalog — language identifier per BCP 47. Recommended for PDF/A A conformance.

output_intent_count: usize

/OutputIntents on the catalog — required by PDF/A for embedded ICC output intent (§6.2.2). Surfaced as the count of intent dicts found.

has_xmp_metadata: bool

/Metadata reference on the catalog. PDF/A requires an embedded XMP packet (§6.7); this is true when present.

Trait Implementations

impl Clone for PdfACatalogSignals

fn clone(&self) -> PdfACatalogSignals

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PdfACatalogSignals

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PdfACatalogSignals

fn default() -> PdfACatalogSignals

Returns the “default value” for a type.

impl Eq for PdfACatalogSignals

impl PartialEq for PdfACatalogSignals

fn eq(&self, other: &PdfACatalogSignals) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
