Struct dmd_core::mem::Mem

pub struct Mem { /* private fields */ }

Implementations

impl Mem

Memory is a Device with a single address range.

pub fn new(start_address: usize, len: usize, is_read_only: bool) -> Mem

pub fn as_slice(&self, range: Range<usize>) -> Result<&[u8], BusError>

Trait Implementations

impl Debug for Mem

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Device for Mem

fn read_byte(&mut self, address: usize, _: AccessCode) -> Result<u8, BusError>

Read from memory at the specified absolute address.

fn write_byte(
    &mut self,
    address: usize,
    val: u8,
    _: AccessCode
) -> Result<(), BusError>

Write to memory at the specified absolute address.

fn load(&mut self, address: usize, program: &[u8]) -> Result<(), BusError>

Load a block of bytes into memory at the specified absolute address. Note that “load” can load into read-only memory.

fn address_range(&self) -> &Range<usize>

fn name(&self) -> &str

fn is_read_only(&self) -> bool

fn read_half(&mut self, address: usize, _: AccessCode) -> Result<u16, BusError>

fn read_word(&mut self, address: usize, _: AccessCode) -> Result<u32, BusError>

fn write_half(
    &mut self,
    address: usize,
    val: u16,
    _: AccessCode
) -> Result<(), BusError>

fn write_word(
    &mut self,
    address: usize,
    val: u32,
    _: AccessCode
) -> Result<(), BusError>

impl Index<usize> for Mem

type Output = u8

The returned type after indexing.

fn index(&self, idx: usize) -> &u8

Performs the indexing (container[index]) operation.
