Implementation

pub fn animation(id: Id, key: []const u8, a: Animation) void {
    var cw = currentWindow();
    const h = id.update(key);
    var aa = a;
    if (reduce_motion) aa.end_time = aa.start_time + 1;
    cw.animations.put(cw.gpa, h, aa) catch |err| switch (err) {
        error.OutOfMemory => {
            log.err("animation got {any} for id {x} key {s}\n", .{ err, id, key });
        },
    };
}
