Implementations

impl Compiled

pub(crate) fn new<B: Backend>( context: Context, views: Vec<ViewTemplate>, ui: &Ui<B>, engine: Weak<Engine<Self, B>>, ) -> Self

Runs compiled code against context for engine, which shows file dialogs and receives their answers and download reports through ui.

fn event( &self, run: impl FnOnce() -> Result<(), AppError>, ) -> Result<(), AppError>

Runs code for an event, then starts the downloads and asks for the dialogs it asked for, even if it failed after asking.

fn receive(&self) -> Result<(), AppError>

fn call(&self, run: impl FnOnce(*const Context) -> bool) -> Result<(), AppError>

Runs a compiled call, turning its false into the failure it recorded.

fn read( &self, read: ReadFn, frame: &Frame, ty: &'static TypeDesc, ) -> Result<Value, AppError>

The value a compiled read gives, owned by the caller.

fn write( &self, binding: &Binding, frame: &Frame, value: Slot, ) -> Result<(), AppError>

Trait Implementations

impl Debug for Compiled

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Logic for Compiled

type Frame = Frame

The locals visible to a piece of UI, such as loop variables and view parameters.

type Value = unsafe extern "C" fn(*const Context, *const u64, *mut u64) -> bool

A value the UI shows, or reads when the user acts, such as a label’s text or a nav item’s value. Each is read as the type the checker gave it.

type Binding = Binding

A place a text field or checkbox shows, and writes the user’s edits to.

type Action = unsafe extern "C" fn(*const Context, *mut u64) -> bool

What a button does when clicked.

type Region = Region

An if, for or view call: UI whose shape depends on state.

type Error = AppError

fn text(&self, text: &ReadFn, frame: &Frame) -> Result<String, AppError>

Errors

fn number(&self, number: &ReadFn, frame: &Frame) -> Result<i64, AppError>

Errors

fn flag(&self, flag: &ReadFn, frame: &Frame) -> Result<bool, AppError>

Errors

fn texts(&self, texts: &ReadFn, frame: &Frame) -> Result<Vec<String>, AppError>

Errors

Errors

fn read_text( &self, binding: &Binding, frame: &Frame, ) -> Result<String, AppError>

Errors

fn read_checked( &self, binding: &Binding, frame: &Frame, ) -> Result<bool, AppError>

Errors

fn write_text( &self, binding: &Binding, frame: &Frame, text: &str, ) -> Result<(), AppError>

Errors

Errors

fn write_number( &self, binding: &Binding, frame: &Frame, number: i64, ) -> Result<(), AppError>

Errors

fn write_texts( &self, binding: &Binding, frame: &Frame, texts: Vec<String>, ) -> Result<(), AppError>

Errors

fn run(&self, action: &ActionFn, frame: &Frame) -> Result<(), AppError>

Errors

fn expand( &self, region: &Region, frame: &Rc<Frame>, ) -> Result<Vec<Shown<Self>>, AppError>

What region shows now, in order: lists of templates, each with its own frame.

fn take_changed(&self) -> StateSet

The states changed since the last call.

fn take_window_requests(&self) -> Vec<WindowRequest>

What code asked of the app’s windows since the last call, in order.
