identity_t

enum identity_t

Special values to be supported as the only parameters of constructors of user-defined algebraic types.

Enumerator
additive_identity	A tag to construct additive identity element. See rng_concept. Any user-defined chsvlib-compatible algebraic type implementing an algebraic structure that is at least an Rng should have a publicly available constructor of the only argument that can have a value, possibly converted, of additive_identity which resolves to integral 0.
multiplicative_identity	A tag to construct multiplicative identity element. See ring_concept. Any user-defined chsvlib-compatible algebraic type implementing an algebraic structure that is at least a ring should have a publicly available constructor of the only argument that can have a value, possibly converted, of multiplicative_identity which resolves to integral 1.
