# STRONG
<p><strong>Stringly typed String for Rust</strong></p>

Rust is a statically and strongly typed systems programming language.  We can create a new type wrapping primitives.
```rust
struct Age(i32);
struct Email(String);
```
There is a problem here, there are two types of strings in Rust, and it is hard to create strong types for both String and &str.

STRONG provides two types owned `StrongBuf` and unsized `Strong`.
```rust
use strong::{StrongBuf, Strong, Email, Validator}

fn login(email: &Strong<Email>, password: &strong<Password>) { .. }

let email: StrongBuf<Email> = ..
let password: StrongBuf<Password> = ..
login(&email, &password);
```

## Getting Started
```rust
use strong::{StrongBuf, Strong, Validator}

enum Password {}
impl<T> Validator for Password {
    type Err = std::convert::Infallible;
}
```
