Implementations
sourceimpl Cache
impl Cache
sourcepub fn draw(&self, bounds: Size<f32>, draw_fn: impl Fn(&mut Frame)) -> Geometry
pub fn draw(&self, bounds: Size<f32>, draw_fn: impl Fn(&mut Frame)) -> Geometry
Draws Geometry
using the provided closure and stores it in the
Cache
.
The closure will only be called when
- the bounds have changed since the previous draw call.
- the
Cache
is empty or has been explicitly cleared.
Otherwise, the previously stored Geometry
will be returned. The
Cache
is not cleared in this case. In other words, it will keep
returning the stored Geometry
if needed.
