Variants

ConfigSet

Host applied (or skipped) a config write.

Fields

widget_id: String

Widget id.

nonce: u64

Map nonce after the write attempt.

bytes: usize

Serialized config size.

changed: bool

true when store bytes changed.

skip: Option<SkipReason>

Present when the write was skipped.

Write

A transport write finished.

Fields

transport: String

Driver name.

ok: bool

Success flag.

duration_ms: u32

Wall time of the write.

error: Option<String>

Error text when ok is false.

Reload

Native / WidgetKit reload attempt.

Fields

performed: bool

Whether reload was invoked.

reason: ReloadOutcome

Outcome detail.

Poll

Host drained pending actions.

Fields

count: usize

Actions returned this poll.

Render

Native / desktop surface painted.

Fields

instance: String

Instance id (family / appWidgetId / window).

nonce: u64

Config nonce observed.

source: String

Transport / prefs source label.

trigger: String

Why paint ran (reload, timeline, …).

lag_ms: u64

Host write → paint lag.

skipped: Vec<SkippedElement>

Elements skipped this paint.
