Ubyte32-option-some

Change-ubyte32-option-some

Modifying constructor for ubyte32-option-some structures.

Syntax

(change-ubyte32-option-some x 
                            [:val <val>])

This is an often useful alternative to make-ubyte32-option-some.

We construct a new ubyte32-option-some structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.
