Enum Unavailable 

pub enum Unavailable {}

The bus, line, and delay of a platform with no spidev or GPIO character device.

No value of it exists, so a LinuxRadio can be named on any platform and opened only on Linux.

Trait Implementations

impl Clone for Unavailable

fn clone(&self) -> Unavailable

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Unavailable

impl Debug for Unavailable

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

Formats the value using the given formatter.

impl DelayNs for Unavailable

fn delay_ns(&mut self, _: u32)

Pauses execution for at minimum ns nanoseconds. Pause can be longer if the implementation requires it due to precision/timing issues.

fn delay_us(&mut self, us: u32)

Pauses execution for at minimum us microseconds. Pause can be longer if the implementation requires it due to precision/timing issues.

fn delay_ms(&mut self, ms: u32)

Pauses execution for at minimum ms milliseconds. Pause can be longer if the implementation requires it due to precision/timing issues.

impl Display for Unavailable

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

Formats the value using the given formatter.

impl Eq for Unavailable

impl Error for Unavailable

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 ErrorType for Unavailable

type Error = ErrorKind

Error type.

impl ErrorType for Unavailable

type Error = ErrorKind

Error type

impl Hash for Unavailable

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 InputPin for Unavailable

fn is_high(&mut self) -> Result<bool, ErrorKind>

Is the input pin high?

fn is_low(&mut self) -> Result<bool, ErrorKind>

Is the input pin low?

impl OutputPin for Unavailable

fn set_low(&mut self) -> Result<(), ErrorKind>

Drives the pin low.

fn set_high(&mut self) -> Result<(), ErrorKind>

Drives the pin high.

fn set_state(&mut self, state: PinState) -> Result<(), Self::Error>

Drives the pin high or low depending on the provided value.

impl PartialEq for Unavailable

fn eq(&self, other: &Unavailable) -> 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 SpiDevice for Unavailable

fn transaction(&mut self, _: &mut [Operation<'_, u8>]) -> Result<(), ErrorKind>

Perform a transaction against the device.

fn read(&mut self, buf: &mut [Word]) -> Result<(), Self::Error>

Do a read within a transaction.

fn write(&mut self, buf: &[Word]) -> Result<(), Self::Error>

Do a write within a transaction.

fn transfer( &mut self, read: &mut [Word], write: &[Word], ) -> Result<(), Self::Error>

Do a transfer within a transaction.

fn transfer_in_place(&mut self, buf: &mut [Word]) -> Result<(), Self::Error>

Do an in-place transfer within a transaction.
