Implementations

impl Error

pub fn msg<S, M>(span: S, message: M) -> Self

where S: Spanned, M: Display + Debug + Send + Sync + 'static,

Construct an error which is made of a single message.

impl Error

pub fn expected_meta<S>( spanned: S, meta: MetaInfo, expected: &'static str, ) -> Self

where S: Spanned,

Error when we got mismatched meta.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

impl Error for Error

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
