Struct BufferMemoryMapper 

pub struct BufferMemoryMapper { /* private fields */ }

Maps a region of memory over a vector. Useful for testing.

Implementations

impl BufferMemoryMapper

pub fn new(size: usize) -> Self

pub fn from_vec(vec: Vec<u8>) -> Self

Trait Implementations

impl MemoryMapper for BufferMemoryMapper

fn create(_address: usize, _size: usize) -> Result<Self, &'static str>

where Self: Sized,

Create a Mapper that maps the given physical address and size.

fn len(&self) -> usize

Returns the maximum length that can be addressed. The end of this memory mapped range is address + len().

fn as_ptr<T>(&self) -> *const T

Returns a pointer to the mapped memory region.

fn as_mut_ptr<T>(&mut self) -> *mut T

Returns a mutable pointer to the mapped memory region.

fn is_empty(&self) -> bool

Returns true if the mapping is empty.

fn as_range(&self, range: impl RangeBounds<usize>) -> &[u8]

Creates an inner range of bytes. The offsets are relative to the base of the mapped memory, e.g. as_range(0..4) will return the first 4 bytes of the mapped memory (a memory mapping to address 0x12340000 will map 0x12340000..0x12340004).

fn as_mut_range(&mut self, range: impl RangeBounds<usize>) -> &mut [u8]

Creates an inner mutable range of bytes.
