A syntax parsing error.

Variants

UnexpectedEof

An unexpected end of file.

ExpectedEof

Expected the end of a file.

MissingEnd(Paired)

Missing the end of a paired token.

MissingEndOr(Paired, char)

Missing the end of a paired token.

Token(LexerError)

An error tokenizing the source code.

UnexpectedToken

An unexpectecd token was encountered in the given context.

ExpectedDeclaration

Expected a declaration.

ExpectedName

Expected a name.

ExpectedStructureMember

Expected a structure member.

ExpectedBlock

Expected a block.

ExpectedModuleBody

Expected a module body.

ExpectedFunctionBody

Expected a function body.

ExpectedEnumBody

Expected an enum body.

ExpectedEnumVariant

Expected an enum variant.

ExpectedIn

Expected the in keyword.

ExpectedFunctionParameters

Expected function parameters.

ExpectedThenOrBrace

Expected the then keyword or a block.

ExpectedColon

Expected a :

ExpectedCommaOrBrace

Expected a , or the end }.

ExpectedMatchBody

Expected a match body.

ExpectedPattern

Expected a pattern.

ExpectedPatternOr(Paired)

Expected a pattern or the end of the pattern match grouping.

ExpectedFatArrow

Expected a =>.

ExpectedCatchBlock

Expected a catch block.

InvalidAssignmentTarget

An assignment can only be done to a lookup (a.b = c) or an index (a[b] = c).

InvalidLabelTarget

The label specified can’t be found or belongs to an invalid target for this expression.

InvalidMapKeyPattern

Map keys must be literal values.

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<'de> Deserialize<'de> for ParseError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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 ErrorKind for ParseError

fn kind(&self) -> &'static str

Returns the summary of the error being raised.

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.

impl Serialize for ParseError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ParseError

impl StructuralPartialEq for ParseError
