Struct Memory

pub struct Memory { /* private fields */ }

Describes the full memory available for a machine.

Implementations

impl Memory

pub fn new() -> Self

Creates an empty (no allocation) memory.

pub fn with_size(size: usize) -> Self

Creates a memory with an arbitrary size.

pub fn len(&self) -> usize

The total memory size.

pub fn is_empty(&self) -> bool

Returns true if the size of the memory is 0.

pub fn store(&mut self, address: Address, datum: Word) -> MemoryResult<()>

Write a Word into the memory at the specified Address.

pub fn load(&self, address: Address) -> MemoryResult<Word>

Reads a Word from the memory at the specified Address.

pub fn array(&self, area: Area) -> MemoryResult<Array>

Reads a full Array from the memory between the specified Addresses.

pub fn slice(&self, area: Area) -> MemoryResult<&[Word]>

Reads a full sliced-Array from the memory between the specified Addresses.

pub fn copy(&mut self, to: Address, data: Array) -> MemoryResult<()>

Writes a full Array into the memory to the specified Address.

pub fn alloc(&mut self, additional_size: usize)

Grow the memory with the specified size.

pub fn free(&mut self, sub_size: usize) -> MemoryResult<()>

Free the memory from the specified size.

Trait Implementations

impl Clone for Memory

fn clone(&self) -> Memory

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Memory

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

Formats the value using the given formatter.

impl Default for Memory

fn default() -> Memory

Returns the “default value” for a type.

impl Index<Address> for Memory

type Output = Word

The returned type after indexing.

fn index(&self, index: Address) -> &Self::Output

Performs the indexing (container[index]) operation.

impl IndexMut<Address> for Memory

fn index_mut(&mut self, index: Address) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.
