Struct ParseError 

pub struct ParseError(/* private fields */);

A single structured error from parsing a WIT package.

Implementations

impl ParseError

pub fn new_syntax(span: Span, message: impl Into<String>) -> ParseError

pub fn kind(&self) -> &ParseErrorKind

Returns the underlying error kind

pub fn kind_mut(&mut self) -> &mut ParseErrorKind

Returns the underlying error kind (mutable).

pub fn highlight(&self, source_map: &SourceMap) -> String

Format this error with source context (file:line:col + snippet)

Trait Implementations

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Eq for ParseError

impl Error for ParseError

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 ParseError

fn from(e: Error) -> ParseError

Converts to this type from the input type.

impl From<ParseErrorKind> for ParseError

fn from(kind: ParseErrorKind) -> ParseError

Converts to this type from the input type.

impl PartialEq for ParseError

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