Implementations

impl Error

pub fn new(kind: ErrorKind, span: Span, source: SourceCode) -> Self

impl Error

pub fn fancy_format_str(&self) -> String

pub fn fancy_format_stderr(&self)

Render a fancy, human-readable output of this error and print it to stderr.

pub fn fancy_format_write<E: Write + Send>(&self, stderr: &mut E)

Render a fancy, human-readable output of this error and print it to a std::io::Write.

fn span_label(&self) -> Option<String>

Create the optional span label displayed as an annotation on the underlined span of the error.

fn code(&self) -> &'static str

Return the unique error code for this variant which can be used to refer users to documentation.

fn spans(&self) -> Vec<SpanLabel>

fn diagnostic(&self) -> Diagnostic

Create the primary diagnostic for a given error.

fn diagnostics(&self) -> Vec<Diagnostic>

Return the primary diagnostic and all further associated diagnostics (if any) of an error.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

Formats the value using the given formatter.

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

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.
