# hex-view
*NOTE:* As of Rust 1.26.0, this crate is no longer necessary because an `&[u8]` can be
formatted as hex using the `:x?` and `:X?` formatters.
Easily format a `&[u8]` as hex.
```rust
use hex_view::HexView;
let ff00_slice: &[u8] = &[255, 0];
assert_eq!(format!("{:x}", HexView::from(&ff00_slice)), "ff00")
```
`HexView::from` also works on anything that implements `AsRef<[u8]>`, such as a `&Vec<u8>`:
```rust
use hex_view::HexView;
let ff00_vec: Vec<u8> = vec![255, 0];
assert_eq!(format!("{:X}", HexView::from(&ff00_vec)), "FF00")
```
