Struct RexactError 

pub struct RexactError {
    pub kind: ErrorCode,
    pub detail: Option<String>,
    pub position: Option<(usize, usize)>,
}

A located catalogue error. position is (line, column), 1-based, counted in Unicode scalar values (docs/07 rule 2).

Fields

kind: ErrorCode

Which catalogue entry this is.

detail: Option<String>

Optional detail appended to the catalogue meaning.

position: Option<(usize, usize)>

Position in the pattern text, when the error relates to one.

Implementations

impl RexactError

pub fn new(kind: ErrorCode) -> Self

Error with no detail or position.

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

Stable code string (RX-...).

impl RexactError

pub fn render(&self, source: &str) -> String

Message followed by the offending source line and a caret under the error column, when the error has a position.

Trait Implementations

impl Eq for RexactError

impl Error for RexactError

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
