# Interning
Interning is the process of storing only one copy of each distinct string value, which must be immutable. This process is used to save memory space and improve performance.

## Usage
Add dependencies to your `Cargo.toml`:
```toml
[dependencies]
interning = "0.2"
```

```rust
use interning::InternedString;
fn main() {
    let s1 = InternedString::new("hello");
    let s2 = InternedString::new("hello");
    assert_eq!(s1, s2);
}
```
