Struct GroupHandle 

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

Opaque handle for an OPC group.

This wrapper type enhances type safety when interacting with OPC COM interfaces, preventing accidental mixing of group and item handles.

Examples

use opc_da_client::GroupHandle;
let handle = GroupHandle(123u32);
assert_eq!(handle.0, 123u32);

Tuple Fields

0: u32
