Enum MotionPref 

pub enum MotionPref {
    Unknown,
    Full,
    Reduced,
}

The OS reduce-motion setting: Reduced is “the user asked for less animation”, Full is “the user did not”, Unknown is “nobody asked the OS”. Spelled as what the user wants rather than as a reduce_motion boolean because the third reading has no place in a boolean, and a missing answer is not the same as a “no”.

Pref because edit already means cosmic-text’s caret Motion by that name, and a crate with two of them would be one letter of ambiguity in every use. The field is system.motion and every binding spells it motion; only Rust sees the longer type name.

Implementations

impl MotionPref

pub const ALL: &'static [MotionPref]

Wire order, as Appearance::ALL.

pub fn name(self) -> &'static str

pub fn parse(name: &str) -> Option<MotionPref>

pub fn code(self) -> u32

The code a C host passes; unknown is 0.

pub fn from_code(code: u32) -> Option<MotionPref>

pub fn is_reduced(self) -> bool

Whether a view should skip or shorten decorative motion. Unknown answers false: a host that cannot tell gets the animations it would have had before this field existed.
