Enum ParserError 

pub enum ParserError {
    ExpectedButFound(String, String),
    ExpectedButReachedEnd(String),
    UnexpectedToken(usize, TokenType),
    UnclosedDirective,
}

When an invalid sequence of tokens is passed to the super::Parser, it will return a ParserError.

Variants

ExpectedButFound(String, String)

Expected one thing but got something else. The type of thing that is being expected can be anything (not necessarily a token).

ExpectedButReachedEnd(String)

Expected something but reached the end of the tokens.

UnexpectedToken(usize, TokenType)

A different token type was expected.

UnclosedDirective

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, 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 From<ParserError> for EvaluatorBuilderError

fn from(parser_error: ParserError) -> Self

Converts to this type from the input type.
