Enum fastobo::error::SyntaxError

pub enum SyntaxError {
    UnexpectedRule {
        expected: Rule,
        actual: Rule,
    },
    ParserError {
        error: PestError<Rule>,
    },
}

A syntax error.

Variants

UnexpectedRule

An unexpected rule was used in FromPair::from_pair.

Example

let pairs = OboParser::parse(Rule::UnquotedString, "hello, world!");
QuotedString::from_pair(pairs.unwrap().next().unwrap()).unwrap_err();

Fields of UnexpectedRule

ParserError

The underlying parser encountered an error.

Example

impl Error for SyntaxError

fn description(&self) -> &str

This method is soft-deprecated.

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

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

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 ocurred.
