Trait embedded_text::rendering::StateFactory

pub trait StateFactory<'a, F: Font> {
    type PixelIteratorState;
    fn create_state(
        &self, 
        cursor: Cursor<F>, 
        parser: Parser<'a>
    ) -> Self::PixelIteratorState;
}

This trait is used to associate a state type to a horizontal alignment option.

Implementing this trait is only necessary when creating new alignment algorithms.

Associated Types
