Enum ParserError 

pub enum ParserError {
    UnexpectedEof,
    UnexpectedToken,
    ParenDepthExceeded,
    InvalidNumber,
}

Parser surface failures (token / grammar level).

Variants

UnexpectedEof

Reached end of input while a production was still pending.

UnexpectedToken

Saw a token that no production could accept.

ParenDepthExceeded

Parenthesis depth exceeded MAX_PAREN_DEPTH.

InvalidNumber

A numeric literal could not be parsed as f64.

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 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.
