start_at - Memory profiling for fun and profit

Graph::start_at

fn start_at(
    self: Graph,
    duration: Duration
) -> Graph

Make the graph start after the given duration as measured from the start of the profiling.

Assuming we have the following graph:

graph()
    .add(allocations())
    .save();

We can make it start later like this:

graph()
    .add(allocations())
    .start_at(s(2))
    .save();
