fn templates( &mut self, frame: &mut Frame<'_>, aliases: &HashMap<LocalId, Alias>, nodes: &Nodes, ) -> Result<List, CodegenError>

Emits nodes as an array of templates.

fn template( &mut self, frame: &mut Frame<'_>, aliases: &HashMap<LocalId, Alias>, node: &Node, slot: &mut Slot<'_>, ) -> Result<TemplateKind, CodegenError>

fn control( &mut self, frame: &mut Frame<'_>, aliases: &HashMap<LocalId, Alias>, node: &Node, slot: &mut Slot<'_>, ) -> Result<TemplateKind, CodegenError>

A control’s template: the functions behind what it shows and edits.

fn display( &mut self, frame: &mut Frame<'_>, aliases: &HashMap<LocalId, Alias>, node: &Node, slot: &mut Slot<'_>, ) -> Result<TemplateKind, CodegenError>

A control that only shows something.

fn input( &mut self, frame: &mut Frame<'_>, aliases: &HashMap<LocalId, Alias>, node: &Node, slot: &mut Slot<'_>, ) -> Result<TemplateKind, CodegenError>

A control the user works: the functions behind what it shows, edits and runs.

fn for_region( &mut self, frame: &mut Frame<'_>, aliases: &HashMap<LocalId, Alias>, head: &Loop, body: &Nodes, slot: &mut Slot<'_>, ) -> Result<(), CodegenError>

Shows body once for each item head loops over.

fn button( &mut self, frame: &mut Frame<'_>, aliases: &HashMap<LocalId, Alias>, (title, selected): (&Dynamic, Option<&Dynamic>), action: &Stmts, slot: &mut Slot<'_>, ) -> Result<(), CodegenError>

A button’s title, whether it is selected if it shows that, and its action.

fn nav_item( &mut self, frame: &mut Frame<'_>, aliases: &HashMap<LocalId, Alias>, item: &NavItem, slot: &mut Slot<'_>, ) -> Result<(), CodegenError>

fn if_region( &mut self, frame: &mut Frame<'_>, aliases: &HashMap<LocalId, Alias>, branches: &[(Rc<Expr>, Nodes)], otherwise: &Nodes, slot: &mut Slot<'_>, ) -> Result<(), CodegenError>

Shows the first branch whose condition holds, or else otherwise, which is the last list.

fn for_value( &mut self, frame: &Frame<'_>, aliases: &HashMap<LocalId, Alias>, head: &Loop, list: &Expr, ) -> Result<FuncId, CodegenError>

Shows the body once per item of a copy of the list, with the item in the loop’s item.

fn for_range( &mut self, frame: &Frame<'_>, aliases: &HashMap<LocalId, Alias>, local: LocalId, start: &Expr, end: &Expr, ) -> Result<FuncId, CodegenError>

Shows the body once per count from start up to, but not including, end, with the count in local.

fn for_place( &mut self, frame: &mut Frame<'_>, aliases: &HashMap<LocalId, Alias>, head: &Loop, place: &Place, nodes: &Nodes, ) -> Result<(FuncId, List), CodegenError>

Shows the body once per item of the list at place, through an alias whose list positions are kept in extra frame slots.

fn view( &mut self, frame: &Frame<'_>, aliases: &HashMap<LocalId, Alias>, view: ViewId, args: &[Expr], ) -> Result<FuncId, CodegenError>

Shows the view’s body in a new frame holding its arguments.

A function the runtime calls with the context, the template’s frame, and extra if there is one. It returns true where build leaves it.

fn expansion( &mut self, frame: &Frame<'_>, aliases: &HashMap<LocalId, Alias>, build: impl FnOnce(&mut Body<'_, '_, '_, M>, Value) -> Result<(), CodegenError>, ) -> Result<FuncId, CodegenError>

A region’s expansion, which tells the sink it’s given what the region shows.

fn shown( &mut self, frame: &Frame<'_>, aliases: &HashMap<LocalId, Alias>, shown: &Dynamic, slot: &mut Slot<'_>, field: usize, ) -> Result<(), CodegenError>

The function that works out shown, put in the template’s field at offset field.

fn value( &mut self, frame: &Frame<'_>, aliases: &HashMap<LocalId, Alias>, shown: &Dynamic, ) -> Result<FuncId, CodegenError>

Writes what the UI shows, owned, to the pointer it’s given.
