The class
erased_type
is an empty struct that serves as a placeholder for a type in situations where the actual type is determined at runtime. For example, in classes that use
type-erased allocators
, the nested typedef
allocator_type
is an alias for
erased_type
.
Notes
erased_type
is removed in LFTS v3 because
std::
pmr
::
polymorphic_allocator
<>
is preferable for type erasure.
