Struct DevMemMemoryMapper 

pub struct DevMemMemoryMapper { /* private fields */ }

A memory mapper that maps over the /dev/mem physical memory device. Only available on Linux with std feature enabled.

Trait Implementations

impl Debug for DevMemMemoryMapper

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

Formats the value using the given formatter.

impl Drop for DevMemMemoryMapper

fn drop(&mut self)

Executes the destructor for this type.

impl<R: RangeBounds<usize>> Index<R> for DevMemMemoryMapper

type Output = [u8]

The returned type after indexing.

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

Performs the indexing (container[index]) operation.

impl MemoryMapper for DevMemMemoryMapper

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

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.
