Module scale_info::form
source · Expand description
Provides form definitions.
The forms provided here are used to generically communicate the mode a type identifier, type definition or structure is using.
The default form is the MetaForm.
It uses MetaType for communicating type identifiers and thus acts as
a bridge from runtime to compile time type information.
The PortableForm is a space-efficient representation
that no longer has any connections to the interning registry and thus
can no longer be used to retrieve information from the
original registry. Its sole purpose is for space-efficient serialization.
Other forms, such as a portable form that is still bound to the registry (also via lifetime tracking) are possible but current not needed.
Enums
A meta meta-type.
Portable form that has its lifetime untracked in association to its interner.
Traits
Trait to control the internal structures of type definitions.
