|
||
------------------------
|
||
|
||
Currently the only stable way to create a `Box` is via the `Box::new` method.
|
||
Also it is not possible in stable Rust to destructure a `Box` in a match
|
||
pattern. The unstable `box` keyword can be used to create a `Box`. An example
|
||
usage would be:
|
||
|
||
```rust
|
||
#![feature(box_syntax)]
|
||
|
||
fn main() {
|
||
let b = box 5;
|
||
}
|
||
```
