Trait gridit::pattern::Pattern[−][src]

pub trait Pattern {
    fn next_action(&mut self) -> Option<Action>;

    fn next_action_peek(&self) -> Option<Action>;

    fn repeat(&self) -> &Repeat;

    fn rest_steps(&self) -> Option<Vec<Step>> { ... }

    fn rest_positions(&self) -> Option<Vec<Position>> { ... }
}

This trait is there to create pattern for the PatternIter. The implemntation should only return one variant of Action.

Variants

  • Action::StepFromOrigin(step_x) if step_x steps outside the grid, this Action will be ignored and next_action will be called again.
  • Action::Jump(position_x) if position_x is outside the grid, this Action will be ignored and next_action will be called again. this action will be ignored and the nexj

Panics

  • if different variants of Action are returned
  • if variant Action::StepFromOrigin does not implement rest_steps.
  • if variant Action::Jump does not implement rest_positions.

Required methods

fn next_action(&mut self) -> Option<Action>[src]

Returns the next Action or None if there are no more Action.

fn next_action_peek(&self) -> Option<Action>[src]

Peeks in the next Action and returns it or None if there is no more Action.

fn repeat(&self) -> &Repeat[src]

Returns a reference to the Repeat.

Provided methods

fn rest_steps(&self) -> Option<Vec<Step>>[src]

Returns the rest of the steps. This must be implemented for Action::StepFromOrigin.

fn rest_positions(&self) -> Option<Vec<Position>>[src]

Returns the rest of the positions. This must be implemented for Action::Jump.
