This lets callers who already have
String
components of a Facet path avoid double-allocating them.The PR is a breaking change since it pushes dealing with
ToString
's allocation (or skipping it :) ) up to the caller. Though for anyone already using&str
orString
their code will continue to compile. Everyone else will need to be explicit and call.to_string
first to get the prior behavior.
