Enum Error

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

Available on crate feature qr_code only.

An error that occurred when building a Data for a QRCode.

Variants

DataTooLong

The data is too long to encode in a QR code for the chosen Version.

InvalidVersion

The chosen Version and ErrorCorrection combination is invalid.

UnsupportedCharacterSet

One or more characters in the provided data are not supported by the chosen Version.

InvalidEciDesignator

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

InvalidCharacter

A character that does not belong to the character set was found.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.

impl From<QrError> for Error

fn from(error: QrError) -> Error

Converts to this type from the input type.

impl PartialEq for Error

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

Tests for self and other values to be equal, and is used by ==.

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

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