Function-definition

Fixtype of Syntheto function definitions.

This is a product type introduced by fty::defprod.

Fields

header — function-header

precondition — maybe-expression

postcondition — maybe-expression

definer — function-definer

A function definition consists of a function header and a function definer. It also has an optional precondition and an optional postcondition. Both must be boolean expressions.
