Struct PatternLibrary 

pub struct PatternLibrary { /* private fields */ }

Library of patterns for invoice field extraction

Implementations

impl PatternLibrary

pub fn new() -> Self

Create a new empty pattern library

pub fn with_language(lang: Language) -> Self

Create a pattern library for a specific language

pub fn add_pattern(&mut self, pattern: FieldPattern)

Add a pattern to the library

pub fn default_spanish() -> Self

Create a pattern library with default Spanish patterns

Returns a new PatternLibrary pre-loaded with Spanish invoice patterns. Users can add custom patterns on top of defaults using add_pattern().

Examples

use oxidize_pdf::text::invoice::{PatternLibrary, FieldPattern, InvoiceFieldType, Language};

// Load Spanish defaults
let mut patterns = PatternLibrary::default_spanish();

// Add custom pattern for specific format
patterns.add_pattern(
    FieldPattern::new(
        InvoiceFieldType::InvoiceNumber,
        r"Invoice\s+#\s*([0-9]+)",
        0.85,
        Some(Language::Spanish)
    ).unwrap()
);

pub fn default_english() -> Self

Create a pattern library with default English patterns

Returns a new PatternLibrary pre-loaded with English invoice patterns.

Examples

use oxidize_pdf::text::invoice::PatternLibrary;

let patterns = PatternLibrary::default_english();

pub fn default_german() -> Self

Create a pattern library with default German patterns

Returns a new PatternLibrary pre-loaded with German invoice patterns.

Examples

use oxidize_pdf::text::invoice::PatternLibrary;

let patterns = PatternLibrary::default_german();

pub fn default_italian() -> Self

Create a pattern library with default Italian patterns

Returns a new PatternLibrary pre-loaded with Italian invoice patterns.

Examples

use oxidize_pdf::text::invoice::PatternLibrary;

let patterns = PatternLibrary::default_italian();

pub fn merge(&mut self, other: PatternLibrary)

Merge patterns from another library into this one

Adds all patterns from other to this library. Useful for combining default patterns with custom patterns.

Examples

use oxidize_pdf::text::invoice::{PatternLibrary, FieldPattern, InvoiceFieldType, Language};

// Start with Spanish defaults
let mut patterns = PatternLibrary::default_spanish();

// Create custom library
let mut custom = PatternLibrary::new();
custom.add_pattern(
    FieldPattern::new(
        InvoiceFieldType::InvoiceNumber,
        r"Ref:\s*([A-Z0-9\-]+)",
        0.8,
        Some(Language::Spanish)
    ).unwrap()
);

// Merge custom into defaults
patterns.merge(custom);

pub fn match_text(&self, text: &str) -> Vec<(InvoiceFieldType, String, f64)>

Match text against all patterns

Trait Implementations

impl Default for PatternLibrary

fn default() -> Self

Returns the “default value” for a type.
