Errors that can occur during decoding.

Variants

Pattern(u16)

A sequence of modules resulted in an unknown pattern.

InvalidModules

A module’s width or spacing is not valid.

WrongStop

The stop code at the end is wrong.

Short

The input was too short.

Length

The code’s length can not fit an allowed sequence of modules.

Checksum

The checksum did not match.

NoMode

The code did not start with a mode signal.

Unexpected(u8)

A symbol occurred in a mode that did not support it or is not implemented.

Latin1

After decoding the data the conversion from Latin 1 failed.

Trait Implementations

impl Debug for DecodingError

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

Formats the value using the given formatter.

impl Display for DecodingError

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

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, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl PartialEq<DecodingError> for DecodingError

fn eq(&self, other: &DecodingError) -> 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.
