Macros
#define	R_HASH_EMPTY   RSIZE_MAX
	Sentinel returned by hash functions for "no value".

Functions
rsize	r_direct_hash (rconstpointer data)
	Pointer-identity hash: treats data as an opaque machine-word and returns it directly.
rboolean	r_direct_equal (rconstpointer a, rconstpointer b)
	Pointer-identity equality: returns TRUE iff a == b.
rsize	r_str_hash (rconstpointer data)
	Hash a NUL-terminated C string.
rsize	r_str_hash_sized (const rchar *data, rssize size)
	Hash a byte string of caller-supplied length.
rboolean	r_str_equal (rconstpointer a, rconstpointer b)
	Equality for NUL-terminated C strings (via strcmp).
