Struct Actions 

pub struct Actions<R: Resource> { /* private fields */ }

The actions a resource publishes, for binding controls that are built outside the view function: rows a table, list or tree creates on demand. Cheap to clone; clones share the published descriptor.

Implementations

impl<R: Resource> Actions<R>

pub fn operation(&self, decl: &ActionDecl<R>) -> Option<ActionSpec>

decl — a bound field edit (tilo_resource::ActionDecl::edit, edit_asking) or verb of another record — as an operation a live row offers (LiveRow::operation), carried out on that record as its person (this app’s notification rule on the app’s row). None for the app’s own resource, whose row edits are ResourceSurface::row_declarations, and where the record is read only here.

pub fn binding<I: 'static>( &self, action: impl Binds<R, I>, ) -> Option<ActionBinding<I>>

The binding of action for a control with input I, or None while the resource does not publish it (an edit bound to view state that is not there now).

pub fn invocation(&self, invoke: Invoke<R>) -> Option<ActionBinding<()>>

The binding of one fully specified invocation, for a button, or None while the resource does not publish it.

pub fn edit_binding<V: 'static>( &self, path: Path<R, V>, edit: impl Fn(&Path<R, V>, V) -> Edit<R> + Send + Sync + 'static, ) -> Option<ActionBinding<V>>

The binding of the field at path for a control with input V: each committed value becomes the field edit edit(path, value). None, and a failure in tests, when the resource has no field edits or the field is #[model(readonly)].

pub fn edit_binding_with<V: 'static, I: 'static>( &self, path: Path<R, V>, edit: impl Fn(&Path<R, V>, I) -> Result<Edit<R>, String> + Send + Sync + 'static, ) -> Option<ActionBinding<I>>

Self::edit_binding for a control whose input I is not the field’s value: a dropdown of “125%” for a scale of 1.25, a slider’s position on a log scale. edit maps each committed input to the field edit, or refuses it, which refuses the input like a value the field cannot take.

pub fn set_binding<V, I>( &self, path: Path<R, V>, value: impl Fn(I) -> Result<V, String> + Send + Sync + 'static, ) -> Option<ActionBinding<I>>

where V: Settable + 'static, I: 'static,

The binding of the field at path for a control with input I: each committed input sets the field to what value makes of it, or is refused where value refuses it. What a settings row binds; the same edit as Self::edit_binding_with and Path::set.

pub fn field_binding<V>(&self, path: Path<R, V>) -> Option<ActionBinding<V>>

where V: Settable + 'static,

Self::set_binding of a control whose input is the field’s value.

pub fn bind<I: 'static, C: ActionControl<I>>( &self, control: C, action: impl Binds<R, I>, ) -> C

control, bound to action. An action the resource does not publish leaves it disabled, and fails tests and tilo-app check.

pub fn bind_invocation<C: ActionControl<()>>( &self, control: C, invoke: Invoke<R>, ) -> C

control (a button), bound to one fully specified invocation.

pub fn effect_binding<E: Effect, I: 'static>( &self, effect: impl Binds<E, I>, ) -> Option<ActionBinding<I>>

The binding of effect effect for a control with input I (Backups::RESTORE for a dropdown of snapshots).

pub fn effect<E: Effect>(&self, effect: &E) -> Option<ActionBinding<()>>

The binding of one fully specified effect, for a button.

pub fn bind_effect<E: Effect, I: 'static, C: ActionControl<I>>( &self, control: C, effect: impl Binds<E, I>, ) -> C

control, bound to effect effect.

pub fn bind_effect_invocation<E: Effect, C: ActionControl<()>>( &self, control: C, effect: &E, ) -> C

control (a button), bound to one fully specified effect.

Trait Implementations

impl<R: Resource> Clone for Actions<R>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
