This library provides a data view for reading and writing data in a byte array.

This library requires feature(generic_const_exprs) to be enabled. whice is a nightly feature.

So you need nightly compiler to use this library.

By default, this library uses little endian as the default endian. But you can override the endian by using BE (for big endian) or NE (for native endian) in fetures flag.

For example, if you want to use big endian,

data-view = { version = "0.2", features = ["BE"] }

It also works with [no_std] environment.

Example

use data_view::DataView;
 
let mut buf: [u8; 16] = [0; 16];

buf.write::<u16>(0, 42);
buf.write::<u32>(2, 123);

assert_eq!(buf.read::<u16>(0), 42);
assert_eq!(buf.read::<u32>(2), 123);
