Enum `ErrorVariant`

enum ErrorVariant<R>

Different kinds of parsing errors.

Variants

ParsingError { positives: alloc::vec::Vec<R>, negatives: alloc::vec::Vec<R> }: Generated parsing error with expected and unexpected Rules
CustomError { message: alloc::string::String }: Custom error with a message

Implementations

`impl<R: RuleType> ErrorVariant<R>`

fn message(self: &Self) -> Cow<'_, str>

Returns the error message for ErrorVariant

If ErrorVariant is CustomError, it returns a Cow::Borrowed reference to message. If ErrorVariant is ParsingError, a Cow::Owned containing "expected [ErrorVariant::ParsingError::positives] [ErrorVariant::ParsingError::negatives]" is returned.

Examples

# use pest::error::ErrorVariant;
let variant = ErrorVariant::<()>::CustomError {
    message: String::from("unexpected error")
};

println!("{}", variant.message());
