Enum DmaBufError 

pub enum DmaBufError {
    BufferTooSmall,
    InsufficientDescriptors,
    UnsupportedMemoryRegion,
    InvalidAlignment(DmaAlignmentError),
    InvalidChunkSize,
}

Available on crate feature unstable only.

Error returned from Dma[Rx|Tx|RxTx]Buf operations.

Variants

BufferTooSmall

The buffer is smaller than the requested size.

InsufficientDescriptors

More descriptors are needed for the buffer size.

UnsupportedMemoryRegion

Descriptors or buffers are not located in a supported memory region.

InvalidAlignment(DmaAlignmentError)

Buffer address or size is not properly aligned.

InvalidChunkSize

Invalid chunk size: must be > 0 and <= 4095.
