Properties

Comparable

Comparable values have a natural order used to order elements in containers (set and map's key). Comparison operators < <= > and >= are available the order of two value.

All types are comparable except: big_map iterable_big_map bls12_381_fr bls12_381_g1 bls12_381_g2 contract lambda list map operation sapling_state sapling_transaction set ticket


Packable

A packable value can be serialised with pack and deserialised with unpack.

All types are packable except: big_map iterable_big_map operation sapling_state ticket


Passable

A passable value can be the parameter of an entrypoint, a lambda and (not inlined) function.

All types are passable except: operation


Storable

A storable value may be a contract's storage element.

All types are storable except: contract operation
