This patch does not migrate tower-filter to use an error type of Box<Error>. Instead, it defines a new type that optionally contains a Box<Error>. The filter layer can be used as part of routing. The router would sequentially attempt to dispatch a request to an inner service. If the request is rejected, it attempts the next one. In this case, allocating a Box<Error> for each attempt is not great. This strategy still fits within the greater picture. tower_filter::error::Error implements the error trait, which means that all other layers that take T: Into<Error> will still work with Filter. Also, only the immediate caller of Filter should care about rejection errors. In which case, Filter will be referenced explicitly. Refs: #131 |
