Enum ChannelError 

#[non_exhaustive]
pub enum ChannelError {
    Implementation(Box<dyn Error + Sync + Send>),
    ReportDescriptor(ParserError),
    HidppNotSupported,
    MessageTypeNotSupported,
    InvalidRawReportLength(usize),
    NoResponse,
    Timeout,
}

Represents an error that occurred when creating or interacting with a HID or HID++ communication channel.

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.

Implementation(Box<dyn Error + Sync + Send>)

Indicates that the concrete implementation of RawHidChannel returned an error.

ReportDescriptor(ParserError)

Indicates that the HID report descriptor could not be parsed.

HidppNotSupported

Indicates that the channel in question does not support HID++.

MessageTypeNotSupported

Indicates that the HID++ channel does not support messages of the given type (short/long).

InvalidRawReportLength(usize)

Indicates that a raw output report was empty or exceeded 64 bytes.

NoResponse

Indicates that no response was received following a request.

Timeout

Indicates that a bounded channel operation did not complete — typically because the device is asleep, out of range, connected to another host, or its transport write is wedged. See HidppChannel::send_with_timeout and HidppChannel::write_raw_report.

Trait Implementations

impl Debug for ChannelError

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

Formats the value using the given formatter.

impl Display for ChannelError

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

Formats the value using the given formatter.

impl Error for ChannelError

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.
