Enum Error 

pub enum Error {
    Lexer(LexerError),
    Parser(ParserError),
    Analysis(AnalysisError),
}

Top-level error type for the EventQL parser.

This enum wraps both lexer and parser errors, providing a unified error type for the entire parsing pipeline.

Variants

Lexer(LexerError)

Error during lexical analysis (tokenization).

Parser(ParserError)

Error during syntactic analysis (parsing).

Analysis(AnalysisError)

Error during static analysis.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<ParserError> for Error

fn from(value: ParserError) -> Self

impl Serialize for Error

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

where __S: Serializer,
