Struct PciMemoryRegion

pub struct PciMemoryRegion<'a> { /* private fields */ }

Implementations

impl PciMemoryRegion<'_>

pub fn new(data: &[u8]) -> PciMemoryRegion<'_>

pub fn new_mut(data: &mut [u8]) -> PciMemoryRegion<'_>

pub unsafe fn new_raw<'a>( data: *mut u8, length: usize, permissions: Permissions, ) -> PciMemoryRegion<'a>

Safety

The returned PciMemoryRegion must not outlive the data.
