Possible errors that can happen during decoding

Variants

IoError

Could not write the output to the output stream/string

DataUnderflow

Expected more bits to decode

DataOverflow

Expected less bits to decode

UnknownDataType

Unknown data type in encoding

DataEcc

Could not correct errors / code corrupt

FormatEcc

Could not read format information from both locations

InvalidVersion

Unsupported / non-existent version read

InvalidGridSize

Unsupported / non-existent grid size read

EncodingError

Output was not encoded in expected UTF8

Trait Implementations

impl Clone for DeQRError

fn clone(&self) -> DeQRError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeQRError

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

Formats the value using the given formatter.

impl Display for DeQRError

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

Formats the value using the given formatter.

impl Error for DeQRError

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<FromUtf8Error> for DeQRError

fn from(_: FromUtf8Error) -> Self

Converts to this type from the input type.

impl PartialEq for DeQRError

fn eq(&self, other: &DeQRError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
