Struct OpyError 

pub struct OpyError {
    pub code: String,
    pub message: String,
    pub span: Option<Span>,
}

A structured frontend error.

Fields

code: String

A stable machine-readable code, e.g. parse-error.

message: String

Human-readable message (not part of the machine contract).

span: Option<Span>

The offending source region, when known.

Implementations

impl OpyError

pub fn new(code: impl Into<String>, message: impl Into<String>) -> OpyError

An error without a source span.

pub fn at( code: impl Into<String>, message: impl Into<String>, span: Span, ) -> OpyError

An error at a source position.

Trait Implementations

impl Clone for OpyError

fn clone(&self) -> OpyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpyError

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

Formats the value using the given formatter.

impl Display for OpyError

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

Formats the value using the given formatter.

impl Eq for OpyError

impl Error for OpyError

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 PartialEq for OpyError

fn eq(&self, other: &OpyError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
