Enum combine::primitives::Error

pub enum Error<T, R> {
    Unexpected(Info<T, R>),
    Expected(Info<T, R>),
    Message(Info<T, R>),
    Other(Box<StdError + Send + Sync>),
}

Enum used to store information about an error that has occurred during parsing.

Variants

Unexpected(Info<T, R>)

Error indicating an unexpected token has been encountered in the stream

Expected(Info<T, R>)

Error indicating that the parser expected something else

Message(Info<T, R>)

Generic message

Other(Box<StdError + Send + Sync>)

Variant for containing other types of errors

Methods

impl<T, R> Error<T, R>

pub fn map_token<F, U>(self, f: F) -> Error<U, R> where     F: FnOnce(T) -> U,

pub fn map_range<F, S>(self, f: F) -> Error<T, S> where     F: FnOnce(R) -> S,

impl<T, R> Error<T, R>

pub fn end_of_input() -> Error<T, R>

Returns the end_of_input error.

pub fn fmt_errors(errors: &[Error<T, R>], f: &mut Formatter) -> Result where     T: Display,     R: Display,

Formats a slice of errors in a human readable way.

let input = r"
  ,123
";
let result = spaces().with(char('.').or(char('a')).or(digit()))
    .parse(State::new(input));
let m = format!("{}", result.unwrap_err());
let expected = r"Parse error at line: 2, column: 3
Unexpected `,`
Expected `.`, `a` or `digit`
";
assert_eq!(m, expected);
