type context = Raw_context.t * id

The type of elements.

Returns true if and only if the set contains no elements. Consumes Gas_repr.read_bytes_cost Z.zero.

Tells whether an elt is a member of the set. Consumes Gas_repr.read_bytes_cost Z.zero

Adds an elt as a member of the set. Consumes Gas_repr.write_bytes_cost <size of the new value>. Returns the new size.

Adds an elt as a member of the set. Consumes Gas_repr.write_bytes_cost <size of the new value>. Returns the new size, and true if the value previously existed.

Removes an elt from the set ; does nothing if not a member. Consumes Gas_repr.write_bytes_cost Z.zero. Returns the freed size, and a boolean indicating if a value was already associated to this key.

Removes all elt from the set. Consumes Gas_repr.write_bytes_cost Z.zero.

This function does not returns the freed size. This is because it would need to fold over all keys or add a size accumulator and no usage exists so far.
