Справочник Rust API

PDF Oxide — это нативный Rust-крейт. Крейт pdf_oxide служит источником истины для всех остальных привязок (Python, JavaScript/WASM, Go, C#, Java и C ABI). На этой странице описана публичная поверхность Rust API для v0.3.69.

# Cargo.toml
[dependencies]
pdf_oxide = "0.3.69"

Опциональные feature-флаги: rendering, signatures, ocr / ocr-tract, parallel, barcodes, office, tsa-client, fips, legacy-crypto.

use pdf_oxide::PdfDocument;          // low-level open + extraction
use pdf_oxide::api::Pdf;             // high-level create / open / edit / save
use pdf_oxide::writer::DocumentBuilder; // fluent PDF generation

Для других языков см. Справочник Python API, Справочник Node.js API или Справочник WASM API, а также Типы и перечисления.

Почти каждый метод, который может завершиться ошибкой, возвращает pdf_oxide::Result<T> (псевдоним для Result<T, pdf_oxide::Error>). В приведённых ниже сигнатурах завершающая обёртка -> Result<...> опускается только там, где это отмечено.

Pdf

pdf_oxide::api::Pdf — это единый высокоуровневый фасад для создания, открытия, извлечения, редактирования и сохранения PDF. Он лениво конструирует DocumentEditor при первом вызове редактирования/извлечения, поэтому большинство методов принимают &mut self.

use pdf_oxide::api::Pdf;

Соответствие PDF/A, PDF/UA и PDF/X

use pdf_oxide::compliance::{validate_pdf_a, PdfAValidator, PdfALevel, ValidationResult};

fn validate_pdf_a(document: &mut PdfDocument, level: PdfALevel) -> Result<ValidationResult>
fn new() -> PdfAValidator

Основные типы данных

Эти структуры несут результаты извлечения. Поля являются публичными.

TextSpan

Фрагмент текста с одинаковым стилем. Возвращается методом extract_spans().

Поле	Тип	Описание
text	String	Содержимое текста
bbox	Rect	Ограничивающий прямоугольник
font_name	String	PostScript-имя шрифта
font_size	f32	Размер шрифта в пунктах
font_weight	FontWeight	Перечисление насыщенности (thin → black)
is_italic	bool	Флаг курсива
is_monospace	bool	Флаг моноширинного шрифта
color	Color	Цвет RGB
char_widths	Vec<f32>	Ширины продвижения для каждого глифа
rotation_degrees	f32	Поворот фрагмента
mcid	Option<u32>	ID размеченного содержимого (тегированные PDF)
heading_level	Option<u8>	Определённый уровень заголовка

TextChar

Один позиционированный символ. Возвращается методом extract_chars().

Поле	Тип	Описание
char	char	Символ Unicode
bbox	Rect	Ограничивающий прямоугольник
font_name	String	PostScript-имя шрифта
font_size	f32	Размер шрифта в пунктах
font_weight	FontWeight	Перечисление насыщенности
is_italic	bool	Флаг курсива
color	Color	Цвет RGB
origin_x, origin_y	f32	Начало текста
advance_width	f32	Продвижение глифа
rotation_degrees	f32	Поворот символа
matrix	Option<[f32; 6]>	Матрица текста
mcid	Option<u32>	ID размеченного содержимого

Word / TextLine / PageText

Word группирует символы в токен (text, bbox, chars, avg_font_size, dominant_font, is_bold, is_italic, mcid). TextLine группирует words с bbox и объединённым text. PageText (из extract_page_text()) собирает spans, chars, page_width и page_height за один проход.

Обработка ошибок

use pdf_oxide::{Error, Result};

Result<T> — это std::result::Result<T, pdf_oxide::Error>. Error — это перечисление, покрывающее ошибки парсинга (Error::InvalidPdf), ошибки ввода-вывода, сбои шифрования/аутентификации и выход индекса страницы за границы.

use pdf_oxide::PdfDocument;

fn main() -> pdf_oxide::Result<()> {
    let doc = PdfDocument::open("input.pdf")?;
    for page in doc.page_indices() {
        let text = doc.extract_text(page)?;
        println!("Page {}: {} chars", page + 1, text.len());
    }
    Ok(())
}

    for text in page.find_text_containing("DRAFT") {
        page.set_text(text.id(), "FINAL")?;
    }
    doc.save_page(page)?;

    // Search across the document
    let hits = doc.search_with_options(
        "configuration",
        pdf_oxide::search::SearchOptions::case_insensitive(),
    )?;
    println!("Found {} matches", hits.len());

    doc.save("output.pdf")?;
    Ok(())
}
