Struct ScratchStats 

pub struct ScratchStats {
    pub capacity: usize,
    pub peak: usize,
    pub overflows: u64,
}

What one frame’s scratch reserve cost and whether it held. A non-zero overflows means some frame fell back to the heap, so peak understates what the frame actually wanted.

Fields

capacity: usize

The reserve’s size in bytes.

peak: usize

The most bytes any frame took from it.

overflows: u64

Requests the reserve declined, sending the caller to the heap.
