# rustpostal
Rust bindings to [libpostal][], a fast statistical parser/normalizer
for street addresses anywhere in the world.
## Usage
```rust
use rustpostal::address;
use rustpostal::expand;
use rustpostal::LibModules;
fn main() -> Result<(), rustpostal::error::RuntimeError> {
let postal_module = LibModules::All;
postal_module.setup()?;
let address = "St Johns Centre, Rope Walk, Bedford, Bedfordshire, MK42 0XE, United Kingdom";
let labeled_tokens = address::parse_address(address, None, None)?;
for (token, label) in &labeled_tokens {
println!("{}: {}", token, label);
}
let expanded = expand::expand_address_with_options(address, Some(["en"].iter()))?;
for expansion in &expanded {
println!("{}", expansion);
}
Ok(())
}
```
## Setup
