Enum DeviceError 

pub enum DeviceError {
    DeviceAccessFailed(Error),
    MemoryMapFailed(Error),
}

Enum representing possible failures when initializing the device.

Initializing a device can fail in two ways:

• DeviceAccessFailed - There is no access to the device file, either because of insufficient permissions or operating system misconfiguration.
• MemoryMapFailed - There is an error when trying to create a mmaped piece of memory to represent device file.

Variants

DeviceAccessFailed(Error)

MemoryMapFailed(Error)

Trait Implementations

impl Debug for DeviceError

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

Formats the value using the given formatter.

impl Display for DeviceError

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

Formats the value using the given formatter.

impl Error for DeviceError

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>)
