This crate provides the `concat_string!` macro for efficiently concatenating string slices into
owned strings. `concat_string!` accepts any number of arguments that implement `AsRef<str>` and
creates a `String` with the appropriate capacity, without the need for format strings and their
associated runtime overhead.

## Example

```rust
#[macro_use(concat_string)]
extern crate concat_string;

fn main() {
    println!("{}", concat_string!("Hello", String::from(" "), "world"));
}
```
