Parser error reported while lexing or parsing source text.

Variants

Lex

Lexing failed before parsing could continue.

Fields

error: LexError

Underlying lexer error.

UnexpectedToken

Parser encountered an unexpected token.

Fields

location: SourceLocation

Source location of the unexpected token.

found: Token

Unexpected token value.

UnexpectedEof

Parser reached end of input unexpectedly.

Fields

location: SourceLocation

Source location where input ended.

InvalidToken

Parser reported an invalid token location.

Fields

location: SourceLocation

Source location of the invalid token.

InvalidExternTypeApplication

Extern signature contained a generic type application.

Fields

location: SourceLocation

Source location of the invalid extern type expression.

Trait Implementations

impl Debug for SyntaxError

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

Formats the value using the given formatter.

impl Display for SyntaxError

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

Formats the value using the given formatter.

impl Error for SyntaxError

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<DE> From<SyntaxError> for CompileError<DE>

where DE: Error + 'static,

fn from(source: SyntaxError) -> Self

Converts to this type from the input type.
