pub struct ReturnStack {
    pub entries: Vec<u32>,
}

The return stack as the ROM left it.

Fields

entries: Vec<u32>

The entries, top (most recent) first.

Implementations

impl ReturnStack

pub fn read( mem: &dyn Memory, layout: &ScreenLayout, ) -> Result<Option<ReturnStack>, Error>

Read it through layout; None when the pointers are not the ROM’s.

pub fn control(&self, layout: &ScreenLayout) -> Option<(bool, u32)>

Whether the stack’s outer loop reads the keys, and how many programs are halted below it; None when the entries do not have the outer loop’s shape at the bottom.
