Summary
DynFuture Drop Can Construct a Dangling Reference
Details

DynFuture is unsound because its Drop implementation transmutes a trait-object reference into unrelated reference types, which constructs an invalid reference from trait object metadata.

This issue was reproduced against dyn-future 3.0.4 under Miri. The crate is unmaintained.
