/// Constant that defines the caps feature name for DMA buffer sharing.
///
/// It has to be used for non-mappable dma-buf only, i.e. when the underlying
/// memory is not mappable to user space. Or when the mapped memory contains
/// non meaningful data. It can be the case for protected content or when the
/// user wants explicitly avoid any software post processing.
///
/// In these cases all elements between the exported and the importer has to work
/// in passthrough mode. This is done by adding this caps feature.
///
/// When the memory is mappable for read and write requests then it is assumes
/// to be a fast path and so this caps feature should not be used. Though
/// according to the dma-buf protocol, while it is mapped it prevents the
/// exporter to migrate the buffer.
///
/// This caps feature should not serve at all the purpose of selecting the
/// [`ALLOCATOR_DMABUF`][crate::ALLOCATOR_DMABUF] allocator during caps negotiation.
/// When the exporter is the upstream element from the importer point of view,
/// the exporter should try to map the dma buffer at runtime (preferably during
/// decide_allocation phase). When it succeeds for `GST_MAP_READWRITE` this caps
/// feature should not be used. This allows scalers, color converts and any image
/// processing filters to work directly on the dma buffer.
/// In this case the importer element should check all incoming memory using
/// [`is_dmabuf_memory()`][crate::is_dmabuf_memory()].
