Enum Backing 

pub(super) enum Backing {
    Contiguous(Frames<false>),
    Discontiguous {
        pmm: DynPmm<'static, false>,
        frame_count: usize,
    },
    Vmo {
        handle: Arc<Handle>,
        frame_count: usize,
    },
}

Available on crate feature full only.

Used to track if the memory underlying the mapping is contiguous

Variants

Contiguous(Frames<false>)

The underlying physical memory is contiguous, and starts at the contained frame

Discontiguous

The underlying physical memory is discontiguous, but all allocated by the same

Fields

pmm: DynPmm<'static, false>

frame_count: usize

Vmo

The mapping is backed by a VMO handle

Fields

handle: Arc<Handle>

frame_count: usize
