Struct libnoentiendo::memory::NullMemory

pub struct NullMemory { /* private fields */ }

Memory that does nothing when read or written to.

Implementations

impl NullMemory

pub fn new() -> Self

Create a new NullMemory that will not warn when read or written to.

pub fn with_warnings(message: &'static str) -> Self

Create a new NullMemory that will warn when read or written to.

Trait Implementations

impl Default for NullMemory

fn default() -> NullMemory

Returns the “default value” for a type.

impl Memory for NullMemory

fn read(&mut self, address: u16) -> u8

Read a byte from this memory at the given address. Implementations may trigger side effects as a result of this read.

fn write(&mut self, address: u16, _value: u8)

Write a byte to this memory at the given address.

fn reset(&mut self)

Reset this memory to its initial state, e.g. after a system reboot. Sometimes this will clear the contents of the memory, like with RAM. Other times this is a no-op, e.g. for ROM.

fn poll( &mut self, _cycles_since_poll: u64, _total_cycle_count: u64 ) -> ActiveInterrupt

Poll this memory to see if an interrupt has been triggered. Implementations may trigger an NMI or IRQ for any implementation-dependent reason.
