Enum ParserError 

pub enum ParserError {
    Generic(String),
    IO {
        context: String,
        source: Error,
    },
    Parse(String),
    Component(String),
    MissingAdoptedStylesheets {
        tag: String,

    Directive(String),
    NotFound(String),
    TsParseError(String),
    Template(Box<Diagnostic>),
}

Error type for WebUI parser.

Variants

Generic(String)

Generic error.

IO

I/O error with context.

Fields

context: String

What operation failed.

source: Error

The underlying I/O error.

Parse(String)

Parse error.

Component(String)

Component error.

MissingAdoptedStylesheets

A component supplied its own <template> wrapper under CssStrategy::Module but did not declare a shadowrootadoptedstylesheets attribute. The framework cannot silently inject the attribute without overriding developer intent on the wrapper, so authoring help is surfaced at build time.

Fields

tag: String

The component tag name (e.g. mp-app).

Css(String)

CSS error.

Html(String)

HTML error.

Directive(String)

Directive error.

NotFound(String)

Entity not found error.

TsParseError(String)

TypeScript parse error.

Template(Box<Diagnostic>)

A build-time template-authoring mistake (e.g. an invalid @event handler or a non-braced w-ref). Carries a structured Diagnostic whose std::fmt::Display is an actionable, color-free report. The CLI colorizes it; FFI/Node/WASM forward the plain text to their host error channel so the application can handle it.

The diagnostic is boxed so this cold error path does not enlarge Result<_, ParserError> on the common success path.

Trait Implementations

impl Debug for ParserError

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

Formats the value using the given formatter.

impl Display for ParserError

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

Formats the value using the given formatter.

impl Error for ParserError

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<Diagnostic> for ParserError

fn from(diagnostic: Diagnostic) -> Self

Converts to this type from the input type.
