Crate pdfplumber_core 

Backend-independent data types and algorithms for pdfplumber-rs.

This crate provides the foundational types (BBox, Char, Word, Line, Rect, Table, etc.) and algorithms (text grouping, table detection) used by pdfplumber-rs. It has no required external dependencies — all functionality is pure Rust.

Modules

• geometry — Geometric primitives: Point, BBox, Ctm, Orientation
• text — Character data: Char, TextDirection, CJK detection
• words — Word extraction: Word, WordExtractor, WordOptions
• layout — Text layout: TextLine, TextBlock, TextOptions
• shapes — Shapes from painted paths: Line, Rect, Curve
• edges — Edge derivation for table detection: Edge, EdgeSource
• table — Table detection: Table, TableFinder, TableSettings
• images — Image extraction: Image, ImageMetadata
• painting — Graphics state: Color, GraphicsState, PaintedPath
• path — Path construction: Path, PathBuilder, PathSegment
• encoding — Font encoding: FontEncoding, EncodingResolver
• error — Errors and warnings: PdfError, ExtractWarning, ExtractOptions
