This software is dual-licensed under the MIT and flashes going off as Diana goes through a revolving door, eyes downcast. To use it without std: downcast-rs = LicenseĬopyright 2020, Ashish Myles (maintainer) and contributors. It supports type parameters, associated types, and constraints. Original concrete types to access additional functionality and performantĭowncast-rs adds this downcasting support to trait objects using only safe Some applications may want to cast these trait objects back to the original concrete types to access additional functionality and performant inlined implementations. But a container of user-defined types requires an open-ended type like a trait object. Implements Downcast for your trait-object-type. Implements DowncastSync and generates downcast -methods for your trait-object-type.
