Enum RepaintPolicy 

pub enum RepaintPolicy {
    Static,
    Live,
    Bounded(Duration),
}

How often the frosted surface’s backdrop must be re-grabbed and re-blurred. The adapter — not core — drives the host’s request_repaint from this; core only names the obligation.

Variants

Static

The backdrop is over still content (dialog, tooltip): grab once, never refresh. The default — cheapest, and correct whenever the content behind the surface is static.

Static means the adapter does not drive repaints for this surface — not that the surface stops compositing. If the host repaints for any other reason (input, animation elsewhere, another surface’s Live), the frost still re-grabs and re-composites that frame. It is “don’t request frames,” not “don’t paint.”

Live

The backdrop is over animating content: refresh every frame. Names an idle-power cost and is required for glass over moving content (otherwise the blur goes stale).

Bounded(Duration)

Refresh periodically — for content that changes on a known cadence.

Trait Implementations

impl Clone for RepaintPolicy

fn clone(&self) -> RepaintPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RepaintPolicy

impl Debug for RepaintPolicy

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

Formats the value using the given formatter.

impl Default for RepaintPolicy

fn default() -> Self

Static — the safe, cheap default for the common dialog/tooltip-over-still-content case.

impl Eq for RepaintPolicy

impl PartialEq for RepaintPolicy

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
