Enum DirectionSpec 

pub enum DirectionSpec {
    SourceToSink,
    SinkToSource,
    Both,
}

Which path(s) a declared plugin applies to.

The default is DirectionSpec::SourceToSink, so an entry with no direction is on the forward path only. DirectionSpec::Both means that, on request: the plugin is instantiated twice, once per direction, rather than sharing one instance, and the sink-to-source chain is the mirror of the declaration order so that wrapping stages nest correctly.

Variants

SourceToSink

SinkToSource

Both
