Struct flexi_parse::error::Error

pub struct Error { /* private fields */ }

An error or collection of errors raised during parsing.

These errors are intended to be reported using ariadne, but an implementation of ToString is provided as an alternative if that is not possible.

Implementations

impl Error

pub fn eprint(&self) -> Result<()>

Available on crate feature ariadne only.

Prints this error to stderr.

impl Error

pub fn add(&mut self, other: Error)

Appends the given error to this one.

pub fn with(self, other: Error) -> Self

Consumes self and other, returning a new error with the contents of both.

    fn parse(input: ParseStream<'_>) -> Result<Self> {
        let mut stmts = vec![];
        let mut errors = vec![];

        while !input.is_empty() {
            match input.parse() {
                Ok(stmt) => stmts.push(stmt),
                Err(err) => {
                    Ast::synchronise(input);
                    errors.push(err);
                }
            }
        }

        if let Some(error) = errors.into_iter().reduce(|acc, err| acc.with(err)) {
            Err(error)
        } else {
            Ok(Ast(stmts))
        }
