}

Error type for all kbd-global operations. Library-wide error type.

Covers hotkey parsing, registration conflicts, backend initialization, device access, permissions, and layer operations.

Variants

Parse(ParseHotkeyError)

A hotkey string like "Ctrl+A" could not be parsed.

AlreadyRegistered

The hotkey is already bound to another action.

BackendInit

The selected backend could not be initialized.

BackendUnavailable

The selected backend is not available on this system.

PermissionDenied

The current user lacks permissions to access input devices.

On Linux, add your user to the input group:

sudo usermod -aG input $USER

DeviceError

An input device operation failed (open, read, ioctl, etc.).

UnsupportedFeature

The requested feature is not supported by the selected backend.

Returned when calling HotkeyManagerBuilder::grab() without the grab feature enabled.

ManagerStopped

The manager has been shut down or the engine thread has exited.

EngineError

An internal engine failure occurred (thread panic, fd error, etc.).

LayerAlreadyDefined

A layer with the given name was already defined.

LayerNotDefined

No layer with the given name has been defined.

EmptyLayerStack

No active layers to pop from the stack.

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<ParseHotkeyError> for Error

fn from(source: ParseHotkeyError) -> Self

Converts to this type from the input type.
