}

Enum to represent possible accessibility-related errors.

Examples

use html_generator::accessibility::Error;

let err = Error::InvalidAriaAttribute {
    attribute: "aria-foo".into(),
    message: "unknown".into(),
};
assert!(err.to_string().contains("aria-foo"));

guideline: Option<String>

Specific WCAG guideline reference

HtmlTooLarge

Error indicating the HTML input is too large to process.

Fields

size: usize

Actual size of the input

max_size: usize

HtmlProcessingError

Error indicating a failure in processing HTML for accessibility.

Fields

message: String

Description of the processing error

source: Option<Box<dyn Error + Send + Sync>>

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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<Error> for HtmlError

Converts an accessibility error into the library-wide crate::error::HtmlError so callers can use ? across module boundaries without an explicit .map_err.

The mapping is lossy on purpose: it collapses structured data such as HTML fragments and WCAG conformance levels into the crate::error::HtmlError::Accessibility variant’s message string. If you need the full structured error, match on the originating Error directly before converting.

Examples

use html_generator::accessibility::Error;
use html_generator::error::HtmlError;

let acc_err = Error::InvalidAriaAttribute {
    attribute: "aria-foo".to_string(),
    message: "not a recognised attribute".to_string(),
};
let html_err: HtmlError = acc_err.into();
assert!(matches!(html_err, HtmlError::Accessibility { .. }));

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<TryFromIntError> for Error

From implementation for TryFromIntError

fn from(err: TryFromIntError) -> Self

Converts to this type from the input type.
