Struct nannou::draw::State

pub struct State<S = Default> where
    S: BaseFloat,  { /* fields omitted */ }

The inner state of the Draw type.

The Draw type stores its State behind a RefCell - a type used for moving mutability checks from compile time to runtime. We do this in order to avoid requiring a mut handle to a draw. The primary purpose of a Draw is to be an easy-as-possible, high-level API for drawing stuff. In order to be friendlier to new users, we want to avoid requiring them to think about mutability and instead focus on creativity. Rust-lang nuances can come later.
