Struct dcc_lsystem::turtle::TurtleLSystemBuilder

pub struct TurtleLSystemBuilder { /* fields omitted */ }

A TurtleLSystemBuilder is used to generate an L-system and a turtle based renderer based don this L-system.

Methods

impl TurtleLSystemBuilder

pub fn new() -> Self

Create a new TurtleLSystemBuilder instance.

pub fn rotate(&mut self, angle: i32) -> &mut Self

Apply a global rotation to the builder. This is useful for modifying the orientation of the data passed to a Renderer.

pub fn token<S: Into<String>>(
    &mut self,
    token: S,
    action: TurtleAction
) -> &mut Self

Associate a token and corresponding action to this builder.

pub fn axiom(&mut self, ident: &str) -> &mut Self

Set the axiom for this builder.

pub fn rule<'a, S: Into<&'a str>>(&mut self, rule: S) -> &mut Self

Add a transformation rule to the builder.

pub fn finish(self) -> (LSystem, TurtleRenderer<TurtleLSystemState>)

Consumes the builder, returning the generated LSystem and a Renderer which can associate tokens in the LSystem to turtle actions.
