Available on crate features e2e-encryption and qrcode only.

Error type describing errors that happen while QR data is being decoded.

Variants

Header

The QR code data is missing the mandatory Matrix header.

Utf8(FromUtf8Error)

The QR code data is containing an invalid, non UTF-8, flow id.

Mode(u8)

The QR code data is using an unsupported or invalid verification mode.

Read(Error)

The QR code data does not contain all the necessary fields.

SharedSecret(usize)

The QR code data uses an invalid shared secret.

Version(u8)

The QR code data uses an invalid or unsupported version.

Keys(KeyError)

The QR code data doesn’t contain valid ed25519 keys.

Trait Implementations

impl Debug for DecodingError

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

Formats the value using the given formatter.

impl Display for DecodingError

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

Formats the value using the given formatter.

impl Error for DecodingError

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.

impl From<Error> for DecodingError

fn from(source: Error) -> DecodingError

Converts to this type from the input type.

impl From<FromUtf8Error> for DecodingError

fn from(source: FromUtf8Error) -> DecodingError

Converts to this type from the input type.

impl From<KeyError> for DecodingError

fn from(source: KeyError) -> DecodingError

Converts to this type from the input type.
