arbitrary_with
accepts for configuration
of the generated Strategy
. Parameters must implement Default

Source§fn output_type(&self, input_type: ColumnType) -> ColumnType
fn output_type(&self, input_type: ColumnType) -> ColumnType
The output ColumnType of this function.
Source§fn propagates_nulls(&self) -> bool
fn propagates_nulls(&self) -> bool
Whether this function will produce NULL on NULL input.
Source§fn introduces_nulls(&self) -> bool
fn introduces_nulls(&self) -> bool
Whether this function will produce NULL on non-NULL input.
Source§fn preserves_uniqueness(&self) -> bool
fn preserves_uniqueness(&self) -> bool

Source§fn is_monotone(&self) -> bool
fn is_monotone(&self) -> bool
Returns true if the function is monotone. (Non-strict; either increasing or decreasing.)
Monotone functions map ranges to ranges: ie. given a range of possible inputs, we can
determine the range of possible outputs just by mapping the endpoints. Read more

fn could_error(&self) -> bool
Whether this function might error on non-error input.
