Enum rppal::system::Error

pub enum Error {
    UnknownModel,
}

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 RPPAL.

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.

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)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
