Struct CnpjMatcher 

pub struct CnpjMatcher { /* private fields */ }

CNPJ matcher with validation and normalization

Implementations

impl CnpjMatcher

pub fn new() -> Self

Create a new CNPJ matcher with validation enabled

pub fn without_validation() -> Self

Create a matcher without check digit validation (faster)

pub fn normalize(&self, cnpj: &str) -> Option<String>

Normalize a CNPJ to 14 digits only

pub fn is_valid(&self, cnpj: &str) -> bool

Validate a CNPJ including check digits

pub fn format(&self, cnpj: &str) -> Option<String>

Format a CNPJ with standard punctuation: XX.XXX.XXX/XXXX-XX

pub fn matches(&self, cnpj1: &str, cnpj2: &str) -> bool

Check if two CNPJs match (normalized comparison)

pub fn score(&self, cnpj1: &str, cnpj2: &str) -> f64

Calculate similarity score between two CNPJs

pub fn root(&self, cnpj: &str) -> Option<String>

Extract the root CNPJ (first 8 digits - company identifier)

pub fn branch(&self, cnpj: &str) -> Option<String>

Extract the branch number (4 digits after root)

pub fn same_company(&self, cnpj1: &str, cnpj2: &str) -> bool

Check if two CNPJs belong to the same company (same root)

pub fn is_headquarters(&self, cnpj: &str) -> bool

Check if this is a headquarters CNPJ (branch = 0001)
