Generate fast XS accessors without run-time compilation
Description
Class::XSAccessor implements fast read, write and read/write accessors in
XS. Additionally, it can provide predicates such as has_foo() for testing
whether the attribute foo is defined in the object. It only works with
objects that are implemented as ordinary hashes. Class::XSAccessor::Array
implements the same interface for objects that use arrays for their
internal representation.
