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. And the crate is unmaintained...

GHSA-67R5-RQWV-9P9Q array-init-cursor is unsound when used with types that implement `Drop`

The Drop implementation will get run twice when using the cursor. This issue does not affect you, if you are using only using the crate with types that are Copy such as u8. This issue also does not affect you, if you are only depending on it through the crate planus...
