Overview

Optional is a tool that generates 'optional' type wrappers around a given type T.

Typically this process would be run using go generate, like this:

//go:generate optional -type=Foo

running this command

optional -type=Foo

in the same directory will create the file optional_foo.go containing a definition of

type OptionalFoo struct {
	...
}

The default type is OptionalT or optionalT (depending on if the type is exported) and output file is optional_t.go. This can be overridden with the -output flag.
