Maybe-function-header

Fixtype of optional function headers.

This is an option type introduced by fty::defoption. Note that defoption is just a wrapper for fty::defflexsum, so there are :none and :some member types, a case macro, and so forth.

Member Types

:none → maybe-function-header-none

Represents that no maybe-function-header is available, i.e., Nothing or None.

:some → maybe-function-header-some

An available maybe-function-header, i.e., Just val or Some val.

Subtopics

Maybe-function-header-case

Maybe-function-header-some

An available maybe-function-header, i.e., Just val or Some val.

Maybe-function-header-none

Represents that no maybe-function-header is available, i.e., Nothing or None.
