pub trait CloneTableShell: Sealed { }Expand description
Boxed cloning for TableShell, so Box<dyn TableShell> is Clone.
Every TableShell + Clone has it; a shell implements Clone and gets
this for free. The trait is sealed: a clone must come from Clone, so
it carries the shell’s narrowing.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
