Struct mathml::parsers::generic_mathml::ParseError

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

Implementations

impl<'a> ParseError<'a>

We implement the ParseError trait here to support the Span type.

pub fn new(message: String, span: Span<'a>) -> Self

pub fn span(&self) -> &Span<'_>

pub fn line(&self) -> u32

pub fn offset(&self) -> usize

pub fn append_message(&mut self, msg: &str)

Trait Implementations

impl<'a> ContextError<LocatedSpan<&'a str>> for ParseError<'a>

Implementing ContextError to support Span

fn add_context(input: Span<'a>, ctx: &'static str, other: Self) -> Self

Creates 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<'a> Debug for ParseError<'a>

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

Formats the value using the given formatter.

impl<'a> ParseError<LocatedSpan<&'a str>> for ParseError<'a>

Further trait implementation for Span

fn from_error_kind(input: Span<'a>, kind: ErrorKind) -> Self

Creates an error from the input position and an ErrorKind

fn append(_input: Span<'a>, _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 from_char(input: Span<'a>, c: char) -> Self

Creates an error from an input position and an expected character

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

Combines two existing errors. This function is used to compare errors generated in various branches of alt.

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

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
