Struct Production 

pub struct Production { /* private fields */ }

Represents production rules in an L-System.

These are rules that may be represented in the form A -> B, where A (called here the ProductionHead) is the symbol that will be matched again, and the symbols after the arrow (in this case the B, called here the ProductionBody is what the symbols matching the head in the input string / axiom will be replaced with.

See:

• Production::head
• Production::body
• System::parse_production

Implementations

impl Production

pub fn new(head: ProductionHead, body: ProductionBody) -> Self

pub fn head(&self) -> &ProductionHead

pub fn body(&self) -> Result<&ProductionBody>

pub fn matches(&self, string: &ProductionString, index: usize) -> bool

Returns true iff this production’s Production::head matches the given string’s index position of the string.

pub fn add_body(&mut self, body: ProductionBody)

pub fn merge(&mut self, other: Self)

Adds all of the body elements from other into self.

pub fn all_bodies(&self) -> &Vec<ProductionBody>

Returns a reference to all of the bodies that this production contains

Trait Implementations

impl Clone for Production

fn clone(&self) -> Production

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Production

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Production

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Production

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SymbolIterable for Production

fn all_symbols_iter(&self) -> impl Iterator<Item = Symbol>

Iterate over all symbols contained in the object.

fn all_symbols<C: FromIterator<Symbol>>(&self) -> C

Creates a collection of all the symbols that [self.all_symbols_iter] iterates over.
