Struct DrawingContext

pub struct DrawingContext {
    pub transform_stack: TransformStack,
    pub style: Resource<Style>,
    pub elapsed_time: f32,
    /* private fields */
}

Fields

transform_stack: TransformStack

style: Resource<Style>

elapsed_time: f32

Amount of time (in seconds) that passed from creation of the engine. Keep in mind, that this value is not guaranteed to match real time. A user can change delta time with which the engine “ticks” and this delta time affects elapsed time.
