Enum Error 

pub enum Error {
    Timeout(ErrorContext),
    Crc(ErrorContext),
    NoCard,
    UnsupportedCommand,
    BadResponse(ErrorContext),
    CardError(CardError),
    WriteError(ErrorContext),
    ReadError(ErrorContext),
    Misaligned,
    InvalidArgument,
    CardLocked,
    BusError(ErrorContext),
}

Errors returned by SD/MMC protocol parsers and drivers.

Recoverable bus / protocol variants carry an ErrorContext pinpointing the phase and (when known) command index that raised them. Caller-facing programming errors (Misaligned, InvalidArgument) and card-state reports (NoCard, CardError, CardLocked) do not.

Variants

Timeout(ErrorContext)

No response from card within the deadline for the wrapped phase.

Crc(ErrorContext)

CRC check failed during the wrapped phase.

NoCard

Card is not responding or not inserted.

UnsupportedCommand

Command index is not supported on this transport.

BadResponse(ErrorContext)

Bad response received during the wrapped phase.

CardError(CardError)

Card returned an error in its R1 response.

WriteError(ErrorContext)

Write operation failed during the wrapped phase.

ReadError(ErrorContext)

Read operation failed during the wrapped phase.

Misaligned

Misaligned address or length passed by the caller.

InvalidArgument

Caller passed an invalid argument.

CardLocked

Card is locked (host needs to unlock before further I/O).

BusError(ErrorContext)

Generic communication error on the bus during the wrapped phase.

Trait Implementations

impl Clone for Error

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

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

Formats the value using the given formatter.

impl PartialEq for Error

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

impl Eq for Error

impl StructuralPartialEq for Error
