Unstable function-object allocation and lifetime capability.

Safety

Function, upvalue, page, and stack handles must be live and belong to this thread’s VM. Counts and sizes must match their layouts, and callers must preserve rooting, open-upvalue ordering, and GC barriers.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
