Structs§

ExactNeighbors: Qualifier for selecting a LRulesSet, where the neighbors of the token are known as constants, with some direct adjacency from the character being matched. This enables “Context-sensitive grammars”; where the context in question simply matches the exact characters neighboring the selected character.
Indexed: Runs the production rules on only the indicies of the string returned by get_indicies().
LRulesQualified: Production rules that depend on surrounding characters when selecting for a specific character, ordered by gradually relaxing constraints.
LRulesSet: A set of rules to apply when a token is matched, with a weight (u8) - the higher the weight compared to the rest of the options, the more likely it will be selected (i.e., this set of production rules satisfies a stochastic grammar).
LSystem: An L-System consists of the current string of tokens, and the rules applied to it.
PredicateNeighbors: Qualifier for selecting a LRulesSet, where neighbors of the token must pass a Boolean predicate. This enables “Context-sensitive grammars”; where the context in question is more flexible than the ExactNeighbors version, and simply has to pass a predicate.
Total: Runs the production rules on every character in the string, every iteration.
Unordered: Runs the production rules on only the characters which had values generated last iteration.

IndexedContext: Trait that represents contexts which can independently track the indicies of the tokens valid for generation in a particular L-System string.
LSystemMode: Trait for qualifying phantom types for the L-System.
ProductionRuleContext: Implement this trait if you want to share an alternative mutable context throughout your production rules.
ProductionRules: Trait for applying production rules bound by LRulesSet, generic in the mechanism by which a selected character is matched.
QualifiedProductionRules: Trait for applying production rules bound by LRulesQualified, generic in the mechanism by which a selected character is matched.

LRulesFunction: Exact match of tokens to a set of production rules via a function.
LRulesFunctionWithIndex: Exact match of tokens to a set of production rules via a function, also including the token’s index in the string being processed.
LRulesHash: Exact match of tokens to a set of production rules via a HashMap.
Predicate: Simple type that qualifies either a prefix or suffix of tokens T.
