#[non_exhaustive]
pub struct WindowOptions {

    pub backend: Backend,
}

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

title: String

The window’s title.

size: Size

The window’s inner size, in logical pixels.

theme: Theme

Colors and sizes of the widgets.

instances: usize

Rectangles and glyphs a frame can hold; more are dropped (and counted).

backend: Backend

The graphics API that draws the window.
