Struct MappingBackingMemory 

pub struct MappingBackingMemory { /* private fields */ }

Implementations

impl MappingBackingMemory

pub fn new( base: UserAddress, memory: Arc<MemoryObject>, memory_offset: u64, ) -> Self

pub fn memory(&self) -> &Arc<MemoryObject>

pub fn read_memory<'a>( &self, addr: UserAddress, bytes: &'a mut [MaybeUninit<u8>], ) -> Result<&'a mut [u8], Errno>

Reads exactly bytes.len() bytes of memory from addr.

Parameters

• addr: The address to read data from.
• bytes: The byte array to read into.

pub fn write_memory(&self, addr: UserAddress, bytes: &[u8]) -> Result<(), Errno>

Writes the provided bytes to addr.

Parameters

• addr: The address to write to.
• bytes: The bytes to write to the memory object.

pub fn zero(&self, addr: UserAddress, length: usize) -> Result<usize, Errno>

pub fn address_to_offset(&self, addr: UserAddress) -> u64

Converts a UserAddress to an offset in this mapping’s memory object.

Trait Implementations

impl Clone for MappingBackingMemory

fn clone(&self) -> MappingBackingMemory

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MappingBackingMemory

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

Formats the value using the given formatter.

impl PartialEq for MappingBackingMemory

fn eq(&self, other: &MappingBackingMemory) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
