Struct ParseError

pub struct ParseError<'a> { /* private fields */ }

Error returned by all parsing methods that return Result.

This error type knows where the error happened, in what direction the string was being parsed, and the kind of error that happened.

Implementations

impl<'a> ParseError<'a>

pub const fn new(parser: Parser<'a>, kind: ErrorKind) -> Self

Constructs a ParseError.

pub const fn other_error( parser: Parser<'a>, extra_message: &'static &'static str, ) -> Self

Constructs a ParseError for an ErrorKind::Other error with a customized error message.

pub const fn copy(&self) -> Self

A const fn equivalent of a clone method.

pub const fn offset(&self) -> usize

Gets the byte offset of this error in the parsed string that the Parser was constructed from.

pub const fn error_direction(&self) -> ParseDirection

The direction that this error happened from, either from the start or the end.

pub const fn kind(&self) -> ErrorKind

The kind of parsing error that this is.

pub const fn panic(&self) -> !

For panicking with an error message, this is called by the unwrap_ctx macro.

Trait Implementations

impl<'a> Clone for ParseError<'a>

fn clone(&self) -> ParseError<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ParseError<'a>

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

Formats the value using the given formatter.

impl<'a> Display for ParseError<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for ParseError<'a>

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