Enum QrError 

pub enum QrError {
    DataTooLong,
    InvalidColor(String),
}

Errors that can occur during QR code generation or rendering.

Converts into modo::Error with HTTP 400 (Bad Request) status. Use QrError::code to get a stable string identifier for each variant.

Variants

DataTooLong

Input data exceeds QR code capacity for the chosen error correction level.

InvalidColor(String)

Invalid hex color string (missing #, wrong length, or non-hex characters).

Implementations

impl QrError

pub fn code(&self) -> &'static str

Returns a stable, namespaced string code for this error (e.g. "qrcode:data_too_long").

Trait Implementations

impl Clone for QrError

fn clone(&self) -> QrError

Returns a duplicate 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

Formats the value using the given formatter.

impl Display for QrError

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

Formats the value using the given formatter.

impl Error for QrError

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(err: QrError) -> Self

Converts to this type from the input type.

impl PartialEq for QrError

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