Trait Implementations

impl<In: Clone + 'static, Out: Clone + 'static> Clone for MapStage<In, Out>

fn clone(&self) -> MapStage<In, Out>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<In: 'static, Out: 'static> Debug for MapStage<In, Out>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<In, Out> GraphStage for MapStage<In, Out>

where In: Clone + Send + 'static, Out: Clone + Send + 'static,

type Shape = FlowShape<In, Out>

fn name(&self) -> &str

fn allocate_shape(&self, _allocator: &mut PortAllocator) -> Self::Shape

fn stage_spec(&self, shape: &Self::Shape) -> StageSpec

fn stage_spec_with_ports( &self, _shape: &Self::Shape, inlets: Vec<AnyInlet>, outlets: Vec<AnyOutlet>, ) -> StageSpec

Builds the StageSpec for this stage, reusing the caller-provided port vectors to avoid re-cloning them from the shape.
