Enum ReadingOrderSource 

pub enum ReadingOrderSource {
    StructureTree,
    XYCut,
    Geometric,
    Simple,
    UserAssigned,
    Fallback,
}

Source of reading order assignment.

Tracks which strategy/method determined the reading order for a span. This follows the SpaceSource pattern for consistency.

Variants

StructureTree

Order from PDF structure tree (Tagged PDF).

Confidence: 1.0 (explicit PDF semantic markup per ISO 32000-1:2008 Section 14.7).

XYCut

Order from XY-Cut recursive partitioning.

Confidence: 0.90 (robust for multi-column layouts).

Geometric

Order from geometric column analysis.

Confidence: 0.85 (good for standard column layouts).

Simple

Order from simple top-to-bottom, left-to-right.

Confidence: 0.75 (basic, works for single-column).

UserAssigned

Order explicitly set by user/API.

Confidence: 1.0 (explicit assignment).

Fallback

Fallback order (e.g., untagged spans in mixed document).

Confidence: 0.65 (best-effort).

Implementations

impl ReadingOrderSource

pub fn default_confidence(&self) -> f32

Get the default confidence for this source type.

pub fn name(&self) -> &'static str

Get strategy name for debugging.

Trait Implementations

impl Clone for ReadingOrderSource

fn clone(&self) -> ReadingOrderSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReadingOrderSource

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

Formats the value using the given formatter.

impl Default for ReadingOrderSource

fn default() -> ReadingOrderSource

Returns the “default value” for a type.

impl PartialEq for ReadingOrderSource

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