Instance Method Details

#keys_to_s ⇒ Hash

Converts keys to Strings. Useful for dealing with SDP::Parser results (which subclasses Parslet::Parser), which returns Parslet::Slice objects in place of String objects, which isn’t helpful in this case.

Returns:

  • (Hash) —

    self, but with Strings instead of Parslet::Slices.
