Enum HidError

pub enum HidError {
    Disconnected,
    NotConnected,
    Message(Cow<'static, str>),
    Other(Box<dyn Error + Send + Sync>),
}

The main error type of this library Currently mostly a wrapper around a platform specific error

Warning All mappings from platform specific errors to platform independent error such as Disconnected or NotConnected are performed on a best effort basis, as it is generally poorly documented by platform apis which operations can throw which errors and in what circumstances

Variants

Disconnected

This error occurs when trying to perform an action on a device which was diconnected after being opened

NotConnected

This error occurs when trying to open a device which is no longer connected

Message(Cow<'static, str>)

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

Implementations

impl HidError

pub fn message(msg: impl Into<Cow<'static, str>>) -> Self

pub fn from_backend(error: impl Into<Box<dyn Error + Send + Sync>>) -> Self

Trait Implementations

impl Debug for HidError

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

Formats the value using the given formatter.

impl Display for HidError

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

Formats the value using the given formatter.

impl Error for HidError

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<Errno> for HidError

fn from(error: Errno) -> Self

Converts to this type from the input type.

impl From<Error> for HidError

fn from(value: Error) -> Self

Converts to this type from the input type.
