An error that occurred during parsing

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unexpected(TextRange)

Unexpected is used when the cause cannot be specified further

UnexpectedExtra(TextRange)

UnexpectedExtra is used when there are additional tokens to the root in the tree

UnexpectedWanted(SyntaxKind, TextRange, Box<[SyntaxKind]>)

UnexpectedWanted is used when specific tokens are expected, but different one is found

UnexpectedDoubleBind(TextRange)

UnexpectedDoubleBind is used when a pattern is bound twice

UnexpectedEOF

UnexpectedEOF is used when the end of file is reached, while tokens are still expected

UnexpectedEOFWanted(Box<[SyntaxKind]>)

UnexpectedEOFWanted is used when specific tokens are expected, but the end of file is reached

DuplicatedArgs(TextRange, String)

DuplicatedArgs is used when formal arguments are duplicated, e.g. { a, a }

RecursionLimitExceeded

RecursionLimitExceeded is used when we’re unable to parse further due to likely being close to a stack overflow.

Trait Implementations

impl Clone for ParseError

fn clone(&self) -> ParseError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

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 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.
