Enum HostSwitchError 

pub enum HostSwitchError {
    Hid(BackendError),
    KeyboardNotFound,
    TargetNotFound,
    Hidpp(String),
    TimedOut {
        operation: &'static str,
    },
    UnsupportedKeyboard,
    HostSlotEmpty {
        host: u8,
    },
}

Failure while arming or running a host-switch link.

Variants

Hid(BackendError)

HID transport-level failure.

KeyboardNotFound

The configured keyboard is not currently reachable.

TargetNotFound

A configured target is not currently reachable.

Hidpp(String)

A required HID++ operation failed.

TimedOut

A required HID++ operation did not complete within its budget.

Fields

operation: &'static str

Description of the operation that exceeded its budget.

UnsupportedKeyboard

The keyboard cannot report its host switch controls to software.

HostSlotEmpty

The device reports the requested host slot as unpaired, so switching to it would strand the device.

Fields

host: u8

The zero-based host slot that has no pairing.

Trait Implementations

impl Error for HostSwitchError

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<BackendError> for HostSwitchError

fn from(source: BackendError) -> Self

Converts to this type from the input type.
