Error Type for dma-heap
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Missing(HeapKind, PathBuf)
The requested DMA Heap doesn’t exist
Access(Error)
An Error occured while accessing the DMA Heap
InvalidAllocation(usize)
The allocation is invalid
NoMemoryLeft
There is no memory left to allocate from the DMA Heap
