Required Methods

fn with_random_nulls(self, null_probability: f64) -> Box<dyn ArrayGenerator>

Replaces the validity bitmap of generated arrays, inserting nulls with a given probability

fn with_nulls(self, nulls: &[bool]) -> Box<dyn ArrayGenerator>

Replaces the validity bitmap of generated arrays with the inverse of nulls, cycling if needed

fn with_nans(self, nans: &[bool]) -> Box<dyn ArrayGenerator>

Replaces the values of generated arrays with NaN values, cycling if needed

Will have no effect if the data type is not a floating point data type

fn with_validity(self, nulls: &[bool]) -> Box<dyn ArrayGenerator>

Replaces the validity bitmap of generated arrays with validity, cycling if needed

fn with_metadata( self, metadata: HashMap<String, String>, ) -> Box<dyn ArrayGenerator>
