Trait Implementations

impl CraneFackError for ParserError

fn get_message(&self) -> (Option<Range<usize>>, String, Option<String>)

Return error message with optional source position and optional source label

fn pretty_print(
    &self,
    source: &str,
    filename: Option<&str>
) -> Result<(), Box<dyn Error>>

Print error to stderr with colors and other fancy stuff

impl Debug for ParserError

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

Formats the value using the given formatter.

impl Display for ParserError

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

Formats the value using the given formatter.

impl Error for ParserError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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
