An error.

Implementations

impl<S: SpanExt> Error<S>

pub fn new(message: impl Into<Cow<'static, str>>) -> Self

Create a new error with the provided message.

pub fn with_span(span: S, message: impl Into<Cow<'static, str>>) -> Self

Create a new error with the provided message and span.

pub fn set_message(&mut self, message: impl Into<Cow<'static, str>>)

Set a new error message for this error, keeping the span.

pub fn set_span(&mut self, span: S)

Set the span of this error.

pub fn to_compile_error(&self) -> S::TokenStream

Convert this error into a TokenStream that will trigger a compile error at the error’s span.

Trait Implementations

impl<S: Debug> Debug for Error<S>

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

Formats the value using the given formatter.

impl<S> Display for Error<S>

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

impl<S: Debug> Error for Error<S>

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

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<S: SpanExt> From<&'static str> for Error<S>

fn from(value: &'static str) -> Self

Converts to this type from the input type.

impl<S: SpanExt> From<String> for Error<S>

fn from(value: String) -> Self

Converts to this type from the input type.
