Struct Error

pub struct Error<'source> {
    pub source: &'source str,
    pub span: Span,
    pub kind: ErrorKind,
}

A compilation error.

Contains a span and a reference to the source code to allow better error formatting.

Fields

source: &'source str

A reference to the source code.

span: Span

The byte range of the source code this error is referencing.

kind: ErrorKind

The type of error.

Implementations

impl Error<'_>

pub fn get_line_column(&self) -> (usize, usize)

Get the line and column of the start of the Error’s span. The fist line and column are 1.

Trait Implementations

impl<'source> Debug for Error<'source>

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.
