Enum cameleon::ControlError

pub enum ControlError {
    Busy,
    Disconnected,
    Io(Error),
    Timeout,
    NotOpened,
    InvalidDevice(Cow<'static, str>),
    BufferTooSmall,
    InvalidData(Box<dyn Error + Send + Sync>),
}

An error type for device control.

Variants

Busy

The device is busy, may be opened by another application.

Disconnected

The device is disconnected from the host.

Io(Error)

IO error.

Timeout

Timeout has occured when receiving stream payload.

NotOpened

The device is not opened.

InvalidDevice(Cow<'static, str>)

The device doesn’t follow the spceicifation.

BufferTooSmall

Buffer is too small to receive data.

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

Try to write invalid data to the device, or received data from the device is semantically invalid. e.g. try to write too large data that will overrun register.

Trait Implementations

impl Debug for ControlError

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

Formats the value using the given formatter.

impl Display for ControlError

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

Formats the value using the given formatter.

impl Error for ControlError

fn source(&self) -> Option<&(dyn Error + 'static)>

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.
