Struct TestingChanged 

pub struct TestingChanged {
    pub shape_type: &'static str,
    /* private fields */
}

Identifies the primitive type category for a testing::*::changed() procedure.

Fields

shape_type: &'static str

Implementations

impl TestingChanged

pub fn new(shape_type: &'static str) -> Self

Trait Implementations

impl<'a, 'tx> Routine<ProcedureContext<'a, 'tx>> for TestingChanged

fn info(&self) -> &RoutineInfo

fn return_type(&self, _input_types: &[Type]) -> Type

fn execute( &self, ctx: &mut ProcedureContext<'a, 'tx>, _args: &Columns, ) -> Result<Columns, RoutineError>

Execute the routine.

fn accepted_types(&self) -> InputTypes

fn propagates_options(&self) -> bool

fn call(&self, ctx: &mut C, args: &Columns) -> Result<Columns, RoutineError>

Calls the routine, automatically propagating Option columns if propagates_options() returns true. The option-propagation behaviour is identical for both contexts, hence the shared default.
