Function pamoja_window_push 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_window_push(
    window: *mut PamojaWindow,
    reading: f32,
)

Adds a reading, dropping the oldest once the window is full.

Passing null is a no-op.

Safety

window must be a live handle from pamoja_window_new, or null.
