Enum Error 

pub enum Error {
    UnknownModel,
    UnknownKernel,
}

Errors that can occur when trying to identify the Raspberry Pi hardware.

Variants

UnknownModel

Unknown model.

DeviceInfo was unable to identify the Raspberry Pi model based on the contents of /proc/cpuinfo, /sys/firmware/devicetree/base/compatible and /sys/firmware/devicetree/base/model.

Support for new models is usually added shortly after they are officially announced and available to the public. Make sure you’re using the latest release of rpi-pal.

You may also encounter this error if your Linux distribution doesn’t provide any of the common user-accessible system files that are used to identify the model and SoC.

UnknownKernel

Unknown kernel.

KernelVersion needed to identify the kernel version from file /proc/version, but was unable to either open the file or parse its content.

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, f: &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(_err: Error) -> Error

impl From<Error> for Error

fn from(_err: Error) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(_err: Error) -> Error
