Crate dataview

The Pod trait marks types whose values can be safely transmuted between byte arrays of the same size.

The DataView type defines read and write data APIs to an underlying byte buffer.

Examples

#[derive(dataview::Pod)]
#[repr(C)]
struct MyType {
	field: i32,
}

// Construct a zero initialized instance
let mut inst: MyType = dataview::zeroed();
assert_eq!(inst.field, 0);

// Use DataView to access the instance
let view = dataview::DataView::from_mut(&mut inst);
view.write(2, &255_u8);

// Create a byte view over the instance
assert_eq!(dataview::bytes(&inst), &[0, 0, 255, 0]);
