Struct ParseError

pub struct ParseError {
    pub reason: Option<ParserErrorReason>,
    pub expected: Vec<ExpectedToken>,
    pub offset: usize,
}

Error for parsing the route

Fields

reason: Option<ParserErrorReason>

A concrete reason why the parse failed.

expected: Vec<ExpectedToken>

Expected token sequences

offset: usize

Additional offset for failures within sub-parsers. Eg. if { parses, but then a bad ident is presented, some offset is needed here then.

Trait Implementations

impl Clone for ParseError

fn clone(&self) -> ParseError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParseError

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

Formats the value using the given formatter.

impl ParseError<&str> for ParseError

fn from_error_kind(_input: &str, _kind: ErrorKind) -> Self

creates an error from the input position and an ErrorKind

fn append(_input: &str, _kind: ErrorKind, other: Self) -> Self

combines an existing error with a new one created from the input position and an ErrorKind. This is useful when backtracking through a parse tree, accumulating error context on the way

fn or(self, other: Self) -> Self

combines two existing error. This function is used to compare errors generated in various branches of [alt]

fn from_char(input: I, _: char) -> Self

creates an error from an input position and an expected character

fn add_context(_input: I, _ctx: &'static str, other: Self) -> Self

create a new error from an input position, a static string and an existing error. This is used mainly in the context combinator, to add user friendly information to errors when backtracking through a parse tree

impl PartialEq for ParseError

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