Struct RawImage 

pub struct RawImage {
    pub bytes: Vec<u8>,
    pub load_addr: u64,
}

A flat byte image mapped at load_addr.

Fields

bytes: Vec<u8>

load_addr: u64

Implementations

impl RawImage

pub fn new(bytes: Vec<u8>, load_addr: u64) -> Self

Construct an image from bytes mapped at load_addr.

pub fn start(&self) -> u64

First valid address.

pub fn end(&self) -> u64

One past the last valid address.

pub fn contains(&self, addr: u64) -> bool

Whether addr lies inside the image.

pub fn offset_of(&self, addr: u64) -> Option<usize>

Translate a virtual address into a byte offset, or None if the address is outside the image.

pub fn read_u8(&self, addr: u64) -> Result<u8>

Read one byte at addr.

pub fn read_u16_le(&self, addr: u64) -> Result<u16>

Read a little-endian 16-bit word at addr. Used to read 6502 vectors (read_u16_le(0xFFFC) is the reset vector).

pub fn slice_at(&self, addr: u64) -> Option<&[u8]>

Borrow a slice starting at addr. Returns None if addr is outside the image.

pub fn bounds(&self) -> (VAddr, VAddr)

Bounds of the image as a VAddr pair, in (start, end) order.
