pub fn active_displays() -> Result<Vec<CGDirectDisplayID>, CGError>

Provides a list of displays that are active (or drawable).

pub fn active_display_count() -> Result<u32, CGError>

Provides count of displays that are active (or drawable).

pub fn hide_cursor(&self) -> Result<(), CGError>

Hides the mouse cursor, and increments the hide cursor count.

pub fn show_cursor(&self) -> Result<(), CGError>

Decrements the hide cursor count, and shows the mouse cursor if the count is 0.

pub fn move_cursor_to_point(&self, point: CGPoint) -> Result<(), CGError>
