    fn extract_location(&self) -> Result<RelRefBuf, Error>

}

Extension trait for option iterators that provide additional convenient accessors.

Required methods

fn find_next(
    &mut self,
    key: OptionNumber
) -> Option<Result<(OptionNumber, &'a [u8]), Error>>

Moves the iterator forward until it finds a matching key or the spot where it should have been.

If found, returns the option number and a byte slice of the value.

Does not consume any options after the matching key.

Provided methods

fn find_next_of<T>(&mut self, key: OptionKey<T>) -> Option<Result<T, Error>> where
    T: TryOptionValueFrom<'a> + Sized, 

Typed version of OptionIteratorExt::find_next.

Moves the iterator forward until it finds a matching key or the spot where it should have been.

If found, returns the value of the option key.

Does not consume any options after the matching key.

fn extract_uri(&self) -> Result<RelRefBuf, Error> where
    Self: Sized + Clone, 

Extracts a URI relative-reference from the remaining URI_PATH and URI_QUERY options, moving the iterator past them.

fn extract_location(&self) -> Result<RelRefBuf, Error> where
    Self: Sized + Clone, 

Extracts a URI relative-reference from the remaining LOCATION_PATH and LOCATION_QUERY options, moving the iterator past them.
