Safe way to allocate and initialize nested arrays directly on the heap in Rust.
To use boxarray in your Rust project, simply add it as a dependency in your Cargo.toml:
toml
[dependencies]
boxarray = "1.0.0"
Then import and use it in your project:
```rust
use boxarray::boxarray;
fn main() { let v = 7.0; let a: Box<[[[f64; 3]; 2]; 4]> = boxarray(v); println!("{a:?}"); } ```
