Function amem_graph_get_confidence 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn amem_graph_get_confidence(
    graph: *mut c_void,
    node_id: u64,
) -> f32

Get a node’s confidence. Returns -1.0 if not found.

Safety

The caller must ensure that all pointer arguments are valid and non-null (unless the function explicitly handles null pointers), and that any pointed-to data is valid for the expected type and lifetime.
