An error from operating the HackRF.

Some errors are recoverable:

• Io & Transfer may just be a failed packet operation on the USB cable, and can potentially be recovered from without giving up on the HackRF.
• AddressRange, ValueRange, TuningRange, and InvalidParameter all mean the arguments to a function were out of range, and may even provide a hint of how to fix them.
• ReturnData means the HackRF replied to a USB transaction with something unintelligible. If this is for a bulk transfer during Sweep mode, it might be possible to recover by stopping and re-entering sweep mode, but most of the time this means something is seriously wrong and nonrecoverable.
• ApiVersion indicates the firmware on the HackRF is too old to support this function. Bail out, and advise the user to update their HackRF’s firmware.

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.

Io(Error)

Underlying OS I/O error.

Transfer(TransferError)

Transfer error from nusb.

AddressRange

The provided address (usually for register I/O) is out of range.

Fields

range: Range<u32>

addr: u32

ValueRange

The provided argument value is out of range.

Fields

range: Range<u32>

val: u32

TuningRange

The provided tuning frequency is out of range.

Fields

range: Range<u64>

val: u64

InvalidParameter(&'static str)

Some argument to a function is invalid in a way not easily expressed as a range.

ApiVersion

The API version of the opened HackRF is too old for this function.

Fields

needed: u16

actual: u16

ReturnData

Returned data from a HackRF didn’t make any sense.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<TransferError> for Error

fn from(source: TransferError) -> Self

Converts to this type from the input type.
