Errors that can occur during WebUI build, render, or inspection operations.

Variants

Io

I/O error (file read/write failures).

Fields

context: String

What operation failed.

source: Error

The underlying I/O error.

ComponentRegistration(String)

Component registration failure.

ComponentDiscovery(String)

Component discovery failure (npm packages or local paths).

Parse

HTML/CSS parsing failure with context about which file failed.

Fields

context: String

What was being parsed.

source: ParserError

The underlying parse error.

Protocol(ProtocolError)

Protocol serialization or deserialization failure.

Serialization(String)

JSON serialization failure.

Rendering(HandlerError)

Handler rendering error.

Trait Implementations

impl Debug for WebUIError

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

Formats the value using the given formatter.

impl Display for WebUIError

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

Formats the value using the given formatter.

impl Error for WebUIError

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<HandlerError> for WebUIError

fn from(source: HandlerError) -> Self

Converts to this type from the input type.

impl From<ProtocolError> for WebUIError

fn from(source: ProtocolError) -> Self

Converts to this type from the input type.
