This package contains just four macros, which enable the creation
of array references to portions of arrays or slices (or things
that can be sliced).
# Examples
Here is a simple example of slicing and dicing a slice into array
references with these macros. Here we implement a simple
little-endian conversion from bytes to `u16`, and demonstrate code
that uses `array_ref!` to extract an array reference from a larger
array. Note that the documentation for each macro also has an
example of its use.
```
#[macro_use]
extern crate arrayref;
fn read_u16(bytes: &[u8; 2]) -> u16 {
bytes[0] as u16 + ((bytes[1] as u16) << 8)
}
// ...
# fn main() {
let data = [0,1,2,3,4,0,6,7,8,9];
assert_eq!(256, read_u16(array_ref![data,0,2]));
assert_eq!(4, read_u16(array_ref![data,4,2]));
# }
