Downcasting with Arc Type in Rust
Learn about downcasting with Arc type in Rust. Explore the conversion processes between Arc<MyStruct> and Arc<dyn MyTrait>.
In Rust, Arc serves as a thread-safe smart pointer, allowing casting from Arc<MyStruct> to Arc<dyn MyTrait>. However, downcasting back to Arc<MyStruct> is complex and unsafe. This entry discusses how to safely implement this conversion and its significance for developers.
