Module program 

The descriptor a compiled program hands the runtime: its states, windows, views and the compiled functions behind every dynamic part of their UI.

nf build emits these as data next to the machine code, laid out as the #[repr(C)] types here say, so their layout is the contract between the two.

Structs

BindingDesc

FrameDesc

The types of a frame’s locals; a frame starts with every local empty.

MenuDesc

A menu: its title and its entries.

MenuEntryDesc

One entry of a menu. Which fields matter depends on kind:

ProgramDesc

Every function returns false after a runtime call recorded why it failed.

RegionDesc

ShortcutDesc

An item’s shortcut, which shortcut holds when present.

SpanDesc

StateDesc

TemplateDesc

One element of a window’s UI. Which fields matter depends on kind:

ViewDesc

WindowDesc

Enums

MenuEntryKind

TemplateKind

Constants

ABI_VERSION

Bumped whenever these layouts or the meaning of a runtime call change, so a program built against another runtime is refused instead of misread.

Type Aliases

ActionFn

Runs a button’s action in a copy of its frame, which it may change.

ExpandFn

Tells sink what a region shows now, through the nf_show_* calls.

InitFn

Writes a state’s starting value to out.

ReadFn

Writes the value a piece of UI shows, such as a string, an int or a bool, to out; frame holds its locals.

WriteFn

Writes value, which it takes ownership of, to a bound place.
