Enum Error 

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

Trait Implementations

impl Clone for Error

Available on crate feature unstable only.

fn clone(&self) -> Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Error

Available on crate feature unstable only.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

Available on crate feature unstable only.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

Available on crate feature unstable only.

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for BlockingError

Available on crate feature unstable only.

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<Error> for MmcError

Available on crate feature unstable only.

fn from(error: Error) -> Self

Converts to this type from the input type.

impl Hash for Error

Available on crate feature unstable only.

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given [Hasher].

impl PartialEq for Error

Available on crate feature unstable only.

fn eq(&self, other: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Error
