Enum InputError 

#[non_exhaustive]
pub enum InputError {
    Keymap,
    Config(&'static str),
    Timer(Error),
    Seat(String),
    Dispatch(Error),
    Io {
        path: PathBuf,
        source: Error,
    },
}

What can go wrong reading input.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Keymap

The keymap did not compile.

A layout that is not installed, a variant that does not exist, an option xkb does not know. xkb reports the detail through its own log, not through a return value, so there is nothing more to pass on here.

Config(&'static str)

The configuration cannot work.

Timer(Error)

A timer could not be created or read.

Seat(String)

libinput could not enumerate the seat through udev, opening it or after a resume. Carries the seat’s name, or resume.

Not “no such seat”: libinput accepts a seat name udev does not know and simply finds no devices on it.

Dispatch(Error)

libinput could not read its devices.

Io

A keymap file could not be read.

Fields

path: PathBuf

The file that could not be read.

source: Error

Why.

Trait Implementations

impl Debug for InputError

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

Formats the value using the given formatter.

impl Display for InputError

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

Formats the value using the given formatter.

impl Error for InputError

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.
