Enum ParserError

pub enum ParserError {
    EmptyScope,
    MissingOperator,
    UnexpectedToken(Token),
    MixingOperators,
    LexerError(LexerError),
}

ParserError is returned when the parser encounters an error.

Variants

EmptyScope

The scope (top-level or set of parentheses) is empty.

MissingOperator

The scope is missing an operator (‘&’ or ‘|’).

UnexpectedToken(Token)

The parser encountered an unexpected token.

MixingOperators

The parser encountered a mix of operators (‘&’ and ‘|’).

LexerError(LexerError)

The parser encountered a lexer error.

Trait Implementations

impl Clone for ParserError

fn clone(&self) -> ParserError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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, f: &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 PartialEq for ParserError

fn eq(&self, other: &ParserError) -> 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.
