Available on crate feature e2e-encryption only.

Error type for the decoding of the QrCodeData.

Variants

NotEnoughData(Error)

The QR code data is no long enough, it’s missing some fields.

NotUtf8(Utf8Error)

One of the URLs in the QR code data is not a valid UTF-8 encoded string.

UrlParse(ParseError)

One of the URLs in the QR code data could not be parsed.

InvalidMode(u8)

The QR code data contains an invalid mode, we expect the login (0x03) mode or the reciprocate mode (0x04).

InvalidVersion(u8)

The QR code data contains an unsupported version.

Base64(DecodeError)

The base64 encoded variant of the QR code data is not a valid base64 string.

InvalidPrefix

The QR code data doesn’t contain the expected MATRIX prefix.

Fields

expected: &'static [u8]

The expected prefix.

got: [u8; 6]

The prefix we received.

Trait Implementations

impl Debug for LoginQrCodeDecodeError

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

Formats the value using the given formatter.

impl Display for LoginQrCodeDecodeError

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

Formats the value using the given formatter.

impl Error for LoginQrCodeDecodeError

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.
