Enum yash_syntax::parser::ErrorCause

pub enum ErrorCause {
    Io(Rc<Error>),
    Syntax(SyntaxError),
}

Types of errors that may happen in parsing.

Variants

Io(Rc<Error>)

Error in an underlying input function.

Syntax(SyntaxError)

Syntax error.

Implementations

impl ErrorCause

pub fn message(&self) -> Cow<'static, str>

Returns an error message describing the error cause.

pub fn label(&self) -> &'static str

Returns a label for annotating the error location.

pub fn related_location(&self) -> Option<(&Location, &'static str)>

Returns a location related with the error cause and a message describing the location.

Trait Implementations

impl Clone for ErrorCause

fn clone(&self) -> ErrorCause

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorCause

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

Formats the value using the given formatter.

impl Display for ErrorCause

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

Formats the value using the given formatter.

impl From<Error> for ErrorCause

fn from(e: Error) -> ErrorCause

Converts to this type from the input type.

impl From<Rc<Error>> for ErrorCause

fn from(e: Rc<Error>) -> ErrorCause

Converts to this type from the input type.

impl From<SyntaxError> for ErrorCause

fn from(e: SyntaxError) -> ErrorCause

Converts to this type from the input type.

impl PartialEq<ErrorCause> for ErrorCause

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