Struct dyn_dyn::DynDynTableEntry

source · [−]

pub struct DynDynTableEntry { /* private fields */ }

Expand description

An entry in a concrete type’s table of downcast-exposed traits.

Each entry represents a single trait object that the concrete type in question can be downcast to. Note that entries will only appear for bare trait object types, i.e. dyn Trait. Trait objects with extra marker types, e.g. dyn Trait + Send, are handled specially by the dyn_dyn_cast! macro and do not appear in a concrete type’s trait table.
