Trait DmaAllocator 

pub trait DmaAllocator {
    // Required methods
    fn alloc_dma(&self, size: usize) -> Result<DmaRegion, DmaAllocError>;
    unsafe fn free_dma(&self, region: DmaRegion);
}

Required Methods

fn alloc_dma(&self, size: usize) -> Result<DmaRegion, DmaAllocError>

Allocates dma.

unsafe fn free_dma(&self, region: DmaRegion)

Safety

The caller must ensure that region was previously allocated by this allocator and has not already been freed.
