Enum DocumentScript 

pub enum DocumentScript {
    Latin,
    CJK,
    RTL,
    Complex,
    Mixed,
}

Document script profile for optimization.

OPTIMIZATION (Issue #1 fix): Detect document primary script once, then skip unnecessary script detection functions for faster boundary detection.

When documents contain only Latin text, we skip RTL and CJK detection entirely. When documents are CJK-dominant, we skip RTL detection. This reduces function call overhead from millions per batch to thousands.

Variants

Latin

Latin-only document (ASCII + extended Latin) Fast path: only check space, TJ offset, geometric gap

CJK

CJK-dominant document (Chinese, Japanese, Korean) Skip RTL detection, use optimized CJK path

RTL

Right-to-left dominant (Arabic, Hebrew) Skip CJK detection, use optimized RTL path

Complex

Complex scripts (Devanagari, Thai, Khmer, etc.) Use specialized complex script detection

Mixed

Mixed scripts or unknown Check all detection functions (slowest path)

Implementations

impl DocumentScript

pub fn detect_from_characters(characters: &[CharacterInfo]) -> Self

Detect document script profile by sampling first 1000 characters.

This optimization reduces boundary detection overhead by skipping unnecessary script detection for documents with known script profiles.

PERFORMANCE: O(min(n, 1000)) sampling, executed once per extraction

Trait Implementations

impl Clone for DocumentScript

fn clone(&self) -> DocumentScript

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DocumentScript

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

Formats the value using the given formatter.

impl PartialEq for DocumentScript

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