Struct MappedOwningPciRegion 

pub struct MappedOwningPciRegion { /* private fields */ }

A memory-mapped OwningPciRegion. This is also a PciRegion. Dropping this unmaps the region.

Implementations

impl MappedOwningPciRegion

pub fn as_ptr(&self) -> *const u8

Returns a constant pointer to the beginning of the memory-mapped region.

pub fn as_mut_ptr(&self) -> *mut u8

Returns a mutable pointer to the beginning of the memory-mapped region.

pub fn len(&self) -> usize

The length of the region.

Unlike PciRegion::len, returns usize.
