[−]
pub trait ParseResultEx<T, E> {
fn chain_err<F, EK>(self, callback: F) -> Result<T, ParseError> where F: FnOnce() -> EK, EK: Into<ParseErrorKind>;
}Additional methods for Result, for easy interaction with this crate.
Required Methods
fn chain_err<F, EK>(self, callback: F) -> Result<T, ParseError> where F: FnOnce() -> EK, EK: Into<ParseErrorKind>
If the Result is an Err then chain_err evaluates the closure,
which returns some type that can be converted to ErrorKind, boxes
the original error to store as the cause, then returns a new error
containing the original error.
