Struct ProviderViewRefreshRequested 

pub struct ProviderViewRefreshRequested {
    pub provider: String,
    pub args: Vec<String>,
}

“re-open the view I own, with these arguments” — asked for from somewhere that holds no activator and returns no Effect (OA.15a).

Why an effect was not enough

AppEffect::OpenProviderView already says this, and every trigger that can return an effect should keep using it. What it cannot serve is a producer that is not running inside a trigger at all: a plugin’s on-event handler returns () by construction (wit/types.wit’s event seam is observation-shaped), and a background task holds neither the dispatcher nor the activator.

The first consumer is the one that made the gap visible. A guest mode’s activation is delivered as minor-activated, and a guest mode has no lifecycle body of its own to hang behaviour on — PluginMode is data with a no-op on_activate (mode_host.rs). So a plugin whose mode is supposed to CHANGE ITS VIEW could observe the activation and do nothing about it, which makes such a mode a label rather than a switch.

The enable-mode precedent, one step further

Event::ModeEnablementRequested is the same shape: the guest cannot reach the activator, so the call is a REQUEST and the Editor applies it. This is that pattern for views, with one deliberate difference — it is a typed event, so BootContext::wake_on_event covers it and the re-scan reaches the screen with no keystroke. A request that only landed on the next keypress would reproduce, exactly, the “works, but only after I hit something” class this codebase has paid for repeatedly.

Fields

provider: String

The provider name, as registered in ProviderViewRegistry.

args: Vec<String>

The view arguments, verbatim. Routed, never read: they are the provider’s own vocabulary, the same contract scan_args carries.

Trait Implementations

impl Clone for ProviderViewRefreshRequested

fn clone(&self) -> ProviderViewRefreshRequested

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProviderViewRefreshRequested

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

Formats the value using the given formatter.

impl Eq for ProviderViewRefreshRequested

impl Event for ProviderViewRefreshRequested

fn event_type_id(&self) -> EventTypeId

The type-id under which this event is registered. Implementors typically delegate to a static to avoid re-allocating the metadata on every call. The macro register_event! generates this for you.

impl PartialEq for ProviderViewRefreshRequested

fn eq(&self, other: &ProviderViewRefreshRequested) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
