Expand description

This trait represents a stateless generator. You pass the grammar & rng in, and it can provide the resulting stream.

Required Methods§

source

fn generate<R: GrammarRandomNumberGenerator>( grammar: &GrammarType, rng: &mut R ) -> Option<StreamType>

This function generates a new value of StreamType, starting from the grammar’s default rule

source

fn generate_at<R: GrammarRandomNumberGenerator>( key: &RuleKeyType, grammar: &GrammarType, rng: &mut R ) -> Option<StreamType>

This function generates a new value of StreamType, starting from a provided rule key

source

fn expand_from<R: GrammarRandomNumberGenerator>( initial: &StreamType, grammar: &GrammarType, rng: &mut R ) -> StreamType

This function generates a new value of StreamType, starting by processing an initial input of StreamType
