Enum PresentationIntent

#[non_exhaustive]
pub enum PresentationIntent {
    SetTitle(String),
    SetInnerSize(Size),
    SetCursor(PresentationCursor),
    WindowChrome(WindowChromeOp),
    Redraw,
}

A window operation that can be retained until presentation is ready.

Values perform no host operation themselves. Titles and sizes are stored without validation; size components are logical pixels and may be negative or non-finite at this layer. The enum is non-exhaustive.

Examples

use ailloli_ui_core::Size;
use ailloli_ui_runtime::app::PresentationIntent;
assert_eq!(PresentationIntent::SetInnerSize(Size::new(800.0, 600.0)), PresentationIntent::SetInnerSize(Size::new(800.0, 600.0)));

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SetTitle(String)

Replace the native window title; an empty title is valid.

SetInnerSize(Size)

Request a logical inner size without normalization.

SetCursor(PresentationCursor)

Replace the current provider-neutral cursor role.

WindowChrome(WindowChromeOp)

Queue a non-coalesced title-bar/window-chrome operation.

Redraw

Request at least one redraw.

Trait Implementations

impl Clone for PresentationIntent

fn clone(&self) -> PresentationIntent

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PresentationIntent

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

Formats the value using the given formatter.

impl PartialEq for PresentationIntent

fn eq(&self, other: &PresentationIntent) -> 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.
