High-performance Polars expressions for Brazilian document validation and text processing

RustPy Toolkit

🚀 High-performance Polars expressions for Brazilian document validation and text processing

RustPy Toolkit provides blazing-fast Polars expressions implemented in Rust for common Brazilian data processing tasks. Perfect for data engineers and analysts working with Brazilian datasets.

✨ Features

• 🏃‍♂️ High Performance: Rust-powered expressions that are significantly faster than pure Python implementations
• 📋 CPF/CNPJ Validation: Validate and format Brazilian CPF and CNPJ documents
• 📱 Phone Validation: Validate and format Brazilian phone numbers
• 🔤 Text Processing: Remove accents, title case conversion, and more
• 🐻‍❄️ Polars Integration: Seamless integration with Polars DataFrames
• 🔧 Easy to Use: Simple, intuitive API

📦 Installation

Install from PyPI using pip:

pip install rustpy-toolkit

Or using uv:

uv add rustpy-toolkit

🚀 Quick Start

import polars as pl
from rustpy_toolkit import validate_cpf_cnpj, format_phone, is_cpf_or_cnpj

# Create a DataFrame with Brazilian documents and phone numbers
df = pl.DataFrame({
    "documento": ["11144477735", "11222333000181", "invalid_doc"],
    "telefone": ["[phone]", "16997184720", "invalid_phone"]
})

# Apply validation and formatting
result = df.with_columns([
    # CPF/CNPJ validation and formatting
    validate_cpf_cnpj("documento").alias("doc_valid"),
    is_cpf_or_cnpj("documento").alias("doc_type"),
    format_cpf_cnpj("documento").alias("doc_formatted"),

    # Phone validation and formatting
    validate_phone("telefone").alias("phone_valid"),
    format_phone("telefone").alias("phone_formatted"),
])

print(result)

📚 Modules

📋 CPF/CNPJ (rustpy_toolkit.cpf_cnpj)

from rustpy_toolkit.cpf_cnpj import validate_cpf_cnpj, is_cpf_or_cnpj, format_cpf_cnpj

# Validate CPF/CNPJ documents
df.with_columns(validate_cpf_cnpj("documento").alias("is_valid"))

# Identify document type
df.with_columns(is_cpf_or_cnpj("documento").alias("doc_type"))  # Returns "CPF", "CNPJ", or None

# Format documents with proper punctuation
df.with_columns(format_cpf_cnpj("documento").alias("formatted"))
# CPF: 111.444.777-35
# CNPJ: 11.222.333/0001-81

📱 Phone (rustpy_toolkit.phone)

from rustpy_toolkit.phone import validate_phone, validate_phone_flexible, format_phone

# Strict validation (requires +55 format)
df.with_columns(validate_phone("telefone").alias("valid_strict"))

# Flexible validation (accepts multiple formats)
df.with_columns(validate_phone_flexible("telefone").alias("valid_flexible"))

# Format to standard Brazilian format
df.with_columns(format_phone("telefone").alias("formatted"))
# Output: [phone]

🔤 Text Utils (rustpy_toolkit.text_utils)

from rustpy_toolkit.text_utils import remove_accents, title_case, pig_latinnify

# Remove accents from text
df.with_columns(remove_accents("texto").alias("clean_text"))

# Convert to title case
df.with_columns(title_case("texto").alias("title_text"))

# Convert to pig latin (fun example)
df.with_columns(pig_latinnify("texto").alias("pig_latin"))

📖 Detailed Examples

Working with Large Datasets

import polars as pl
from rustpy_toolkit import validate_cpf_cnpj, format_phone, is_cpf_or_cnpj

# Load a large dataset
df = pl.read_csv("large_dataset.csv")

# Process millions of records efficiently
processed = df.with_columns([
    validate_cpf_cnpj("cpf_cnpj").alias("document_valid"),
    is_cpf_or_cnpj("cpf_cnpj").alias("document_type"),
    format_cpf_cnpj("cpf_cnpj").alias("document_formatted"),
    validate_phone_flexible("phone").alias("phone_valid"),
    format_phone("phone").alias("phone_formatted"),
])

# Get statistics
stats = processed.group_by("document_type").agg([
    pl.count().alias("count"),
    pl.col("document_valid").sum().alias("valid_count")
])

Data Cleaning Pipeline

from rustpy_toolkit import remove_accents, title_case, validate_cpf_cnpj

# Clean and standardize data
cleaned = df.with_columns([
    # Clean text fields
    remove_accents("nome").alias("nome_clean"),
    title_case("nome").alias("nome_formatted"),

    # Validate documents
    validate_cpf_cnpj("documento").alias("documento_valid"),

    # Filter only valid records
]).filter(pl.col("documento_valid"))
