Implementations

impl CelParserError

pub fn location(&self) -> Option<(usize, usize)>

Returns the line and column number where the error occurred, if available.

This is useful for providing detailed feedback to users about syntax errors. The location is 1-indexed (line 1, column 1).

Example

use rust_cel_parser::parse_cel_program;

let result = parse_cel_program("1 + & 2"); // Invalid operator
if let Err(e) = result {
    if let Some((line, col)) = e.location() {
        println!("Error at line {}, column {}: {}", line, col, e);
        assert_eq!(line, 1);
        assert_eq!(col, 5);
    }
}

Trait Implementations

impl Debug for CelParserError

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

Formats the value using the given formatter.

impl Display for CelParserError

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

Formats the value using the given formatter.

impl Error for CelParserError

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 From<Box<Error<Rule>>> for CelParserError

fn from(source: Box<Error<Rule>>) -> Self

Converts to this type from the input type.

impl From<Error<Rule>> for CelParserError

fn from(err: Error<Rule>) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for CelParserError

fn from(source: FromUtf8Error) -> Self

Converts to this type from the input type.
