Struct DummyError

pub struct DummyError;

A ZST that implements RowanNomError when details or context don’t matter

Trait Implementations

impl Clone for DummyError

fn clone(&self) -> DummyError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DummyError

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

Formats the value using the given formatter.

impl Default for DummyError

fn default() -> DummyError

Returns the “default value” for a type.

impl Display for DummyError

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

Formats the value using the given formatter.

impl Error for DummyError

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<Lang: Language> RowanNomError<Lang> for DummyError

fn from_message(_message: &str) -> Self

Generic error, should probably be ultimately removed

fn from_expected(_position: usize, _message: &str) -> Self

fn from_expected_eof(_range: Range<usize>) -> Self

fn from_unexpected_eof(_position: usize) -> Self

Creates error: Attempted to read a token when there are none remaining

fn from_unexpected_token( _span: Range<usize>, _expected: Lang::Kind, _found: Lang::Kind, ) -> Self

fn with_context(self, _ctx: &'static str) -> Self
