Function track_new 

pub fn track_new<T>(name: &str, value: T) -> T

Arguments

• name - A descriptive name for the variable (used in event output)
• value - The value being tracked (returned unchanged)

Returns

The input value, unchanged. This allows chaining:

let x = track_new("x", 42);
assert_eq!(x, 42);

Examples

Basic usage:

let data = track_new("data", vec![1, 2, 3]);
let events = get_events();
assert!(events[0].is_new());

With structs:

struct Point { x: i32, y: i32 }
let p = track_new("point", Point { x: 10, y: 20 });
