pub fn widths(layout: &Layout<'_>, allocation: &Allocation) -> Vec<u32>Expand description
How many bytes each of an allocation’s spill slots takes on the stack.
The same question as [width] asked of a whole allocation at once, and public because
crate::slots needs it to say how big a cell holding a spilled value has to be, which it has
to know before there is a frame to ask.
