Struct TrackingModel 

pub struct TrackingModel {
    pub init_count: Arc<AtomicUsize>,
    pub update_count: Arc<AtomicUsize>,
    pub view_count: Arc<AtomicUsize>,
    pub value: i32,
}

A test model that tracks lifecycle calls with atomic counters.

Useful for verifying that init/update/view are called the expected number of times.

Fields

init_count: Arc<AtomicUsize>

Counter for init calls.

update_count: Arc<AtomicUsize>

Counter for update calls.

view_count: Arc<AtomicUsize>

Counter for view calls.

value: i32

Internal state for testing.

Implementations

pub fn with_counters( init_count: Arc<AtomicUsize>, update_count: Arc<AtomicUsize>, view_count: Arc<AtomicUsize>, ) -> Self

Create a new tracking model with shared counters.

pub fn init_calls(&self) -> usize

Get the current init count.

pub fn update_calls(&self) -> usize
