Struct NestedView 

pub struct NestedView;

Use this as a marker type for using this layout as a nested field within another layout.

Example

use binary_layout::prelude::*;

binary_layout!(icmp_header, BigEndian, {
  packet_type: u8,
  code: u8,
  checksum: u16,
  rest_of_header: [u8; 4],
});
binary_layout!(icmp_packet, BigEndian, {
  header: icmp_header::NestedView,
  data_section: [u8], // open ended byte array, matches until the end of the packet
});
