Enum DeviceError 

pub enum DeviceError {
    NoDeviceFound,
    NoDeviceFoundAtPath(String),
    IO(Error),
    Hid(HidError),
    ShortRead(usize, usize),
    InvalidReport(u8),
}

Errors that can occur when opening, initializing, or reading from devices.

Variants

NoDeviceFound

The Device failed to open

NoDeviceFoundAtPath(String)

The device at path failed to open

IO(Error)

A device operation resulted in a std::io::Error

Hid(HidError)

A device operation resulted in a hidapi::HidError

ShortRead(usize, usize)

A device report was not the required length

InvalidReport(u8)

A device report was invalid

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>)

🔬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 DeviceError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<HidError> for DeviceError

fn from(source: HidError) -> Self

Converts to this type from the input type.
