Struct ItemHandle 

#[repr(transparent)]
pub struct ItemHandle(pub u32);

Opaque handle for an OPC item.

Similar to GroupHandle, this ensures type-safe identification of tags within an OPC group.

Examples

use opc_da_client::ItemHandle;
let handle = ItemHandle(456u32);
assert_eq!(handle.0, 456u32);

Tuple Fields

0: u32
