Struct FullParsingError

pub struct FullParsingError<'a, Reason> {
    pub loc: FullLocation<'a>,
    pub reason: Option<Reason>,
    pub src: Cow<'a, str>,
}

A final error with information about where in the source did the error occur.

This should be constructed at the top-level of a parser as the final action before returning the result. Main ways to construct this are ParsingError::with_src_loc and [Parser::with_full_error]

To print the source line of the error along with the reason & location, use the value returned by its method with_source_line, this will alter its Display implementation.

Fields

loc: FullLocation<'a>

Where the error occured.

reason: Option<Reason>

What the parser expected to see at the location of the error. If None, then the error was recoverable and the parser didn’t have any particular reason.

src: Cow<'a, str>

The source code to which the error points.

Implementations

impl<Reason> FullParsingError<'_, Reason>

pub fn own(self) -> FullParsingError<'static, Reason>

Unbind the error from the lifetimes by allocating the file path if it hasn’t been already.

Trait Implementations

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
