1//! PDF parsing backend and content stream interpreter for pdfplumber-rs.
2//!
3//! This crate implements Layer 1 (PDF parsing via pluggable backends) and
4//! Layer 2 (content stream interpretation) of the pdfplumber-rs architecture.
5//! It depends on pdfplumber-core for shared data types.
6//!
7//! # Key types
8//!
9//! - [`PdfBackend`] — Trait for pluggable PDF parsing backends
10//! - [`LopdfBackend`] — Default backend using the `lopdf` crate
11//! - [`ContentHandler`] — Trait for receiving events from content stream interpretation
12//! - [`TextState`] — PDF text state machine (fonts, matrices, positioning)
13//! - [`CMap`] — Character code to Unicode mapping (ToUnicode CMaps)
14//! - [`FontMetrics`] — Font width metrics for character positioning
