Enum WindowKnowledge 

pub(crate) enum WindowKnowledge {
    Fullscreen(bool),
    Unknowable,
}

Whether the platform can answer “is a fullscreen window present?”. Linux Wayland uses Unknowable; everywhere else passes a concrete Fullscreen(bool). Exists so the combining logic in pause_decision is one pure function with one truth-table test, instead of three near-identical chains duplicated per platform.

Variants

Fullscreen(bool)

Unknowable

Trait Implementations

impl Clone for WindowKnowledge

fn clone(&self) -> WindowKnowledge

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WindowKnowledge

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

Formats the value using the given formatter.

impl PartialEq for WindowKnowledge

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