#[non_exhaustive]
pub enum Error {
    Timeout,
    ResponseCrc,

    ResponseTimeout,
    DataTimeout,
    FifoOverrun,

}

Error returned by host operations.

Variants (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.

Timeout

A hardware operation did not complete in time.

ResponseCrc

Response CRC check failed.

DataCrc

Data CRC or end-bit error.

ResponseTimeout

Card did not respond to the command.

DataTimeout

Data transfer timed out.

FifoOverrun

FIFO under- or overrun during a transfer.

StartBitError

Data start-bit error.

HardwareLocked

Command could not be loaded (hardware locked).

ResponseError

Controller flagged a response error.

DmaError

IDMAC transfer error.

NoCard

No card present in the slot.

BufferNotDmaCapable

Buffer lies in a region the IDMAC cannot reach.

Unsupported

Operation not supported.
