sinkable

[ <!: ]

The sinkable protocol defines how a value should consume other values.

Typically, sinks perform some side-effect with each value.

Here is an example implementation of sinkable for files.

  <!: .def (Files.t, (line) => self.stream\send(line + '\n'))

sink

sinkable.<!: datum unknown :: (success (status ok:, value unknown) | error (status err:, message string))

Perform some side-effecting action to consume a datum.

Since a side-effect is performed (which may fail or present no data), this message returns a result.
