Modules

• interfaces
  Types that implement InterfaceType, used in examples.
• trait_objects
  Ffi-safe trait objects for individual traits.

Structs

• DynTrait
  DynTrait implements ffi-safe trait objects, for a selection of traits.
• RequiredTraits
  Describes which traits are required and enabled by the I: InterfaceType that this RequiredTraits is created from.
• TypeInfo
  Metadata about a type.
• UneraseError
  Error for DynTrait<_> being downcasted into the wrong type with one of the *downcasted* methods.
• VTable_Ref
  A pointer to the vtable of DynTrait.

Traits

• DeserializeDyn
  Describes how D is deserialized, using a proxy to do so.
• InterfaceType
  Defines the usable/required traits when creating a DynTrait<Pointer<()>, ThisInterfaceType>.
• IteratorItem
  The way to specify the expected Iterator::Item type for an InterfaceType.
• IteratorItemOrDefault
  Gets the expected Iterator::Item type for an InterfaceType, defaulting to () if it doesn’t require Iterator to be implemented.
• MakeRequiredTraits
  For constructing a RequiredTraits constant.
• MakeVTable
  Csontructs a vtable.
• SerializeProxyType
  Determines the intermediate type a SerializeType implementor is converted into, and is then serialized.
• SerializeType
