Struct AnnotationAppearance 

pub struct AnnotationAppearance {
    pub has_normal: bool,
    pub has_rollover: bool,
    pub has_down: bool,
    pub states: Vec<String>,
}

Summary of an annotation’s §12.5.5 appearance dictionary (Table 168) as surfaced on PdfAnnotation::appearance.

Each of the three entries (/N normal — required, /R rollover, /D down) is either a single appearance stream or a subdictionary of streams keyed by appearance state; Self::states is the union of state names across all three (empty when every present entry is a single stream).

Fields

has_normal: bool

/N — normal appearance present (Table 168 requires it, but the enumeration is tolerant of producers that omit it).

has_rollover: bool

/R — rollover appearance present (defaults to /N per Table 168 when absent).

has_down: bool

/D — down appearance present (defaults to /N).

states: Vec<String>

Union of appearance-state names across the /N / /R / /D subdictionaries, sorted and de-duplicated.

Trait Implementations

impl Clone for AnnotationAppearance

fn clone(&self) -> AnnotationAppearance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnnotationAppearance

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

Formats the value using the given formatter.

impl Default for AnnotationAppearance

fn default() -> AnnotationAppearance

Returns the “default value” for a type.

impl Eq for AnnotationAppearance

impl PartialEq for AnnotationAppearance

fn eq(&self, other: &AnnotationAppearance) -> 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.
