Enum CaptureError

pub enum CaptureError {
    MissingInterface,
    MissingFifo,
    Io(Error),
}

Error during the --capture phase of extcap.

Variants

MissingInterface

The --extcap-interface argument is required during the --capture phase of extcap, but is not provided.

MissingFifo

Error caused by missing --fifo argument from the command line. This is expected to be passed by Wireshark when invoking an extcap for capturing, and is needed to write the output of the packet capture to.

Io(Error)

IO Error while trying to open the given fifo. Since the fifo is necessary to send the captured packets to Wireshark, implementations are recommended to clean up and terminate the execution. Additionally, the error can be printed onto stderr. If Wireshark picks that up, it will show that to the user in an error dialog.

Trait Implementations

impl Debug for CaptureError

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

Formats the value using the given formatter.

impl Display for CaptureError

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

Formats the value using the given formatter.

impl Error for CaptureError

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.
