Enum rn2903::Error

pub enum Error {
    ConnectionFailed(Error),
    WrongDevice(String),
    BadResponse(String, String),
    CannotPause,
    TransceiverBusy,
    Disconnected(Error),
}

The primary error type used for fallible operations on the RN2903.

Variants

ConnectionFailed(Error)

The connection to the RN2903 was impossible for some reason. Perhaps an invalid port was specified, or this program does not have permission to access the specified port.

WrongDevice(String)

The device to which the serial link is connected does not appear to be a RN2903, because it did not respond to sys get ver correctly.

BadResponse(String, String)

The device returned a response that doesn't make sense, given the command that was issued.

CannotPause

The device is operating in a mode which prevents MAC functionality from being paused, but a pause was requested.

TransceiverBusy

The transceiver is busy with another operation, or is under the control of the MAC, and cannot be used to perform the requested operation.

Disconnected(Error)

The program has become disconnected from the RN2903 module due to an I/O error. It is possible the device was physically disconnected, or that the host operating system closed the serial port for some reason.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, fmt: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Error for Error

fn description(&self) -> &str

Deprecated since 1.41.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

impl From<Error> for Error

fn from(err: Error) -> Error

Performs the conversion.

impl From<Error> for Error

fn from(err: Error) -> Error

Performs the conversion.
