pub enum BasePipeline<'a, P: 'a> {
    Pipeline(&'a P),
    Index(usize),
    None,
}
Expand description

A reference to a parent pipeline. The assumption is that a parent and derivative/child pipeline have most settings in common, and one may be switched for another more quickly than entirely unrelated pipelines would be.

Variants

Pipeline(&'a P)

Referencing an existing pipeline as parent.

Index(usize)

A pipeline in the same create pipelines call.

The index of the parent must be lower than the index of the child.

None

No parent pipeline exists.
