Enum Error 

pub enum Error {
    Syntax(ParseError),
    Parse(ParseError, Span),
}

A failure at the syntax or parse stage.

Variants

Syntax(ParseError)

The syntax layer (Muon) rejected the input.

Parse(ParseError, Span)

The input is a valid Muon tree but not a valid Elly program (this subset), with the span of the source the error is about.

Implementations

impl Error

pub fn span(&self) -> Span

The span of the source the error is about; a syntax error is at an offset, so its span is empty.

pub fn report(&self, name: &str, text: &str) -> String

Reports the error in the document name, whose text is text, as name:line:column: message and the line, the span underlined (see source::report).

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl PartialEq for Error

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