Module reflection

Safe access to object reflection metadata.

Structs

• AccessPath
• AccessPathObj
  A path from a root value to a nested one (ffi.reflection.AccessPath).
• AccessStep
• AccessStepObj
  One step of an AccessPath: an attribute, array index or map key (ffi.reflection.AccessStep).
• FieldFlags
  The reflection flags of one field (C++ refl::AttachFieldFlag and friends), combined with |.
• FieldGetter
  Resolves a reflected field once, then uses its registered C ABI getter.
• ObjectDef
  Registers the reflection of the object type N, as C++ refl::ObjectDef<N> does: the metadata, each #[reflect] field, the methods and the type attributes.
• TypeAttrColumn
  A registry-owned type-attribute column indexed by runtime type.

Enums

• SEqHashKind
  How the structural engines treat instances of a type (C++ _type_s_eq_hash_kind).

Traits

• ShallowCopy
  A copy of an object’s own fields under a fresh object header (the C++ copy constructor), which __ffi_shallow_copy__ returns.
• UnsafeInit
  An object type whose object can start with every field undefined, for reflection to set the fields: C++ UnsafeInit.

Functions

• get_type_attr
  Look up one type attribute and copy it into an owning value.
• unsafe_init^⚠
  An object of T with every field undefined, as C++ make_object<T>(UnsafeInit{}) makes one, for reflection to set the fields through their setters.
