Struct RichError 

pub struct RichError { /* private fields */ }

An error enriched with context.

Records what happened and where.

Implementations

impl RichError

pub fn new(error: Error, span: Span) -> RichError

Create a new error with context.

pub fn with_file(self, file: Arc<str>) -> Self

Add the source file where the error occurred.

Enable pretty errors.

pub fn error(&self) -> &Error

pub fn span(&self) -> &Span

Trait Implementations

impl Clone for RichError

fn clone(&self) -> RichError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RichError

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

Formats the value using the given formatter.

impl Display for RichError

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

Formats the value using the given formatter.

impl Error for RichError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error<Rule>> for RichError

fn from(error: Error<Rule>) -> Self

Converts to this type from the input type.

impl From<RichError> for Error

fn from(error: RichError) -> Self

Converts to this type from the input type.

impl From<RichError> for String

fn from(error: RichError) -> Self

Converts to this type from the input type.

impl Hash for RichError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RichError

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