Schema.pipe

Appends stage to this schema.

struct Schema(DriveMode mode, S...)

pipe

(

alias NextStage

NextArgs...

)

(

auto ref NextArgs nextArgs

)

if (

isStage!NextStage

)

Parameters

NextStage: Stage to be appended
NextArgs: Arguments to be passed to NextStage constructor when the pipeline is instantiated.

Type: auto

The returned value depends on NextStage and the first (source) stage.

If NextStage is a filter, a Schema is returned that allows appending further stages to it.
If NextStage is an active sink that implements input range interface, the pipeline is instantiated as a reference-counted struct object that also exposes the input range interface.
If NextStage is a sink and the first stage is an active source that implements output range interfaece, the pipeline is instantiated as a reference-counted struct object that also exposes the output range interface.
If neither first stage nor NextStage have range interface, the pipeline is instantiated on the stack and and executed immediately.
It is an error if both first stage and NextStage have range interfaces.
