source · [−]
pub trait View {

}
Expand description

A data view for reading and writing data in byte array.

Examples

use data_view::View;

let mut buf = [0; 16];

buf.write_at(1, 42_u16);
assert_eq!(buf.read_at::<u16>(1).unwrap(), 42);

Required methods

Reads a value of type E: Endian from view.

Examples
use data_view::View;

let buf = [42];

assert_eq!(buf.read_at::<u8>(0), Some(42));
assert_eq!(buf.read_at::<u16>(1), None);

Writes a value of type E: Endian to data view.

Examples
use data_view::View;

let mut buf = [0];

assert_eq!(buf.write_at(0, 42_u8), Ok(()));
assert_eq!(buf.write_at(1, 123_u16), Err(()));
