Enum ParserError 

pub enum ParserError {
    ExpectedIdent(u32, u32, String),
    MissingFromStatement(u32, u32),
    ExpectedKeyword(u32, u32, &'static str, String),
    ExpectedSymbol(u32, u32, Symbol, String),
    UnexpectedToken(u32, u32, String),
    ExpectedType(u32, u32),
    UnexpectedEof,
}

Errors that can occur during syntactic analysis.

These errors are produced by the parser when the token sequence does not match the expected grammar of EventQL.

Variants

ExpectedIdent(u32, u32, String)

Expected an identifier but found something else.

Fields: (line, column, found_token)

MissingFromStatement(u32, u32)

The query is missing a required FROM statement.

Fields: (line, column)

ExpectedKeyword(u32, u32, &'static str, String)

Expected a specific keyword but found something else.

Fields: (line, column, expected_keyword, found_token)

ExpectedSymbol(u32, u32, Symbol, String)

Expected a specific symbol but found something else.

Fields: (line, column, expected_symbol, found_token)

UnexpectedToken(u32, u32, String)

An unexpected token was encountered.

Fields: (line, column, found_token)

This is a general error for tokens that don’t fit the current parse context.

ExpectedType(u32, u32)

Expected a type name but found something else.

Fields: (line, column, found_token)

This occurs when defining a type conversion operation but the left side is not a type.

UnexpectedEof

The input ended unexpectedly while parsing.

This occurs when the parser expects more tokens but encounters the end of the token stream.

Trait Implementations

impl Debug for ParserError

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

Formats the value using the given formatter.

impl Display for ParserError

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

Formats the value using the given formatter.

impl Error for ParserError

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

Converts to this type from the input type.

impl Serialize for ParserError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
