pub enum Error {
    Io(IoError),
    QueueEmpty,
    String(Utf8Error),
    Sys(Errno),
}

Joydev Error type

Variants

Io(IoError)

Errors caused by Rust standard io (File::open, Read, etc.).

QueueEmpty

This can be returned from io_control::get_event when the device is open in non-blocking mode and there aren't any events left on the device.

String(Utf8Error)

Errors caused by C string to Rust string conversion.

Sys(Errno)

Errors caused by ioctls.

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Errno> for Error

fn from(errno: Errno) -> Self

Performs the conversion.

impl From<Error> for Error

fn from(error: IoError) -> Self

Performs the conversion.

impl From<Utf8Error> for Error

fn from(error: Utf8Error) -> Self

Performs the conversion.
