Struct pir_8_emu::vm::Memory

pub struct Memory { /* fields omitted */ }

Mostly-transparent wrapper for a heap-allocated 64KiB u8 array with R/W tracking

Methods

impl Memory

pub fn new() -> Memory

Create fresh zero-initialised unread and unwritten memory

pub fn iter_rw(&self) -> MemoryReadWrittenIterator

Get an iterator over the read and written memory cells

Examples

let mut memory = Memory::new();
memory[0x4B0B] = memory[0x00A1];
println!("{}", memory[0x4B0B]);
memory[0xEB0B] = 0x12;

// (address, value, was_read, was_written)
assert_eq!(memory.iter_rw().collect::<Vec<_>>(),
           &[(0x00A1, 0x00, true, false),
             (0x4B0B, 0x00, true, true),
             (0xEB0B, 0x12, false, true)]);

pub fn reset_rw(&mut self)

Mark all of memory as unread and unwritten

Examples

let mut memory = Memory::new();
memory[0x4B0B] = memory[0x00A1];
println!("{}", memory[0x4B0B]);
memory[0xEB0B] = 0x12;

memory.reset_rw();
assert_eq!(memory.iter_rw().collect::<Vec<_>>(), &[]);
