Enum qr2term::QrError

pub enum QrError {
    DataTooLong,
    InvalidVersion,
    UnsupportedCharacterSet,
    InvalidEciDesignator,
    InvalidCharacter,
}

QrError encodes the error encountered when generating a QR code.

Variants

DataTooLong

The data is too long to encode into a QR code for the given version.

InvalidVersion

The provided version / error correction level combination is invalid.

UnsupportedCharacterSet

Some characters in the data cannot be supported by the provided QR code version.

InvalidEciDesignator

The provided ECI designator is invalid. A valid designator should be between 0 and 999999.

InvalidCharacter

A character not belonging to the character set is found.

Trait Implementations

impl Clone for QrError

fn clone(&self) -> QrError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QrError

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

Formats the value using the given formatter.

impl Display for QrError

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

Formats the value using the given formatter.

impl Error for QrError

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 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<QrError> for QrError

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